Updated Thursday, March 9, 2023, by Traducciones al Español Estamos traduciendo nuestros guías y tutoriales al Español. Es posible que usted esté viendo una traducción generada automáticamente. Estamos trabajando con traductores profesionales para verificar las traducciones de nuestro sitio web.

Este proyecto es un trabajo en curso. to try this guide with a $ credit, This credit will be applied to any valid services used during your first days. The is an open source version manager for, NVM is easy to understand and works on any POSIX-compliant shell (for example, sh or bash). NVM allows you to easily install and manage different versions of Node and switch between them on a per-shell basis.

This guide describes how to install NVM, and how to use it to install and run different versions of Node. Node changes quickly and testing applications with different versions is often difficult. Since NVM enables quick and effortless switching between Node versions, it is much easier to test version compatibility and upgrades with multiple libraries.

1. NVM stores the Node versions and associated modules inside your user directory, so sudo does not have to be used.
2. NVM also simplifies the installation and compilation process because Node versions no longer have to be obtained directly from the distribution channel.
3. A complete NVM installation consists of the following high-level steps.

Each step is described below. These instructions show you how to install NVM and are generally valid for most Linux distributions, although some of the,bashrc directives might vary slightly on different shells. You can install and use NVM regardless of whether you have installed Node already.

1. Install NVM using either curl or wget, To install NVM using curl, run the following command: curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash To install NVM using wget, run the following command: wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash Note You can also install NVM using GIT or with a manual download and installation. Consult the GIT section of the for detailed instructions.
2. Source the new instructions NVM added to,bashrc during the installation process. You can either exit and re-enter the shell console, or manually source your,bashrc file. This file is almost always located at the root of your home directory. source ~/.bashrc As an alternate method, you can execute the new instructions in the same console to apply them immediately. export NVM_DIR=”$HOME/.nvm” && \. “$NVM_DIR/nvm.sh” # This loads nvm && \. “$NVM_DIR/bash_completion” # This loads nvm bash_completion Note NVM uses the following environmental variables. We recommend leaving them at the default settings. Use caution if you decide to change them for any reason.
   • NVM_DIR: NVM’s installation directory.
   • NVM_BIN: The location where Node, the Node Package Manager (NPM), and global packages for the active version of Node are installed.
   • NVM_INC: The directory for Node’s include files (for building C/C++ add-ons).
   • NVM_CD_FLAGS: The flags used to maintain compatibility with zsh,
   • NVM_RC_VERSION: The version from the,nvmrc file (if used).
3. Confirm you have successfully installed NVM. command -v nvm If the installation was successful, NVM returns nvm, If you see the message nvm: command not found, confirm the original installation completed successfully and repeat step #2 of this section to source the,bashrc file. nvm
4. You can confirm the version of NVM that is running with the following command: nvm -version

NVM’s install command downloads, compiles, and installs the specified version of Node. You can install as many versions of Node as you want.

1. To install the latest version of Node, run the following: nvm install node After a successful install, NVM displays information about the installation. Now using node v15.5.1 (npm v7.3.0) Creating default alias: default -> node (-> v15.5.1) Note When used in a NVM command, node is an alias for the latest version of Node. The first version of Node you installed automatically becomes the default version. A new shell instantiates with the current version of Node set to default, The alias system refers to the system-installed version of Node (if any).
2. To install a specific version of Node, specify the major or minor release number. You can preview a list of all available Node versions with the ls-remote command. nvm ls-remote NVM displays a long list of available versions in the following format: v5.12.0 v6.0.0
3. Install any additional versions of Node you want to use. You can specify either a major or minor release of Node to install. When you install a new version of Node, NVM immediately begins using it and designates it as the current version. nvm install 13.10.1 # Specific minor release nvm install 14 # Specify major release only Note If you only specify the major release number for a Node version, NVM installs the latest version of that release. You can determine the latest version of each release from the output of nvm ls-remote, Node also displays the exact version it selected after installation (for example, Now using node v14.15.4 ). If you specify a version of Node that is not available, NVM responds with the error message Version ‘15.0.2’ not found – try ‘nvm ls-remote’ to browse available versions.

Review all installed versions of Node with the ls command. nvm ls NVM returns a list of all Node versions and aliases, along with an arrow indicating the current version. Here is a sample output: v13.10.1 v14.15.4 -> v15.5.1 default -> node (-> v15.5.1) iojs -> N/A (default) node -> stable (-> v15.5.1) (default) stable -> 15.5 (-> v15.5.1) (default)

To select a different version of Node, use the nvm use command. Specify either the version number of Node (major or minor release) or an alias such as node, nvm use node or nvm use 14 NVM confirms it is now using the new version. Now using node v14.15.4 You can also confirm the current version of Node with nvm current, nvm current NVM again returns the current version number. v14.15.4 Note You can also confirm the version of Node currently in use with node -v, To go back to using the system’s version of Node, run the command nvm use system, To switch to a different version of Node and immediately open a Node console, use nvm run, The run command is very similar to nvm use in all other respects. nvm run node NVM confirms it is now running the selected version of Node and returns a Node prompt. Running node v15.5.1 (npm v7.3.0) Welcome to Node.js v15.5.1. Type “.help” for more information. > You might find it convenient to refer to a Node version by a different or easier to remember name. NVM already provides some pre-made defaults such as default and node, which refers to the latest version. But you can use the alias command to change the value of an existing alias or create a brand-new alias.

1. Use the nvm alias command to change the default Node version. Follow the alias keyword with the default alias and the new version of Node it should reference. nvm alias default 14 NVM confirms the new value for the alias. default -> 14 (-> v14.15.4)
2. Use the nvm alias command to create a new alias. The following example defines a new maintenance alias as Node version 13.10.1. nvm alias maintenance 13.10.1 NVM confirms the new alias. maintenance -> 13.10.1 (-> v13.10.1)
3. You can display all of the new and old aliases with the nvm ls command. nvm ls

Any Node.js version can be in one of the following three release phases: “Current”, “Active Long Term Support (LTS)”, and “Maintenance”. The LTS release version of Node.js includes new features, bug fixes, and updates that have been approved to be a part of the release line.

This section shows you how to install the latest LTS version of Node.js using NVM. Use the following command to install the latest LTS version of Node.js on your system: nvm install -lts You should see the following output: Installing latest LTS version. Downloading and installing node v16.15.1. Downloading https://nodejs.org/dist/v16.15.1/node-v16.15.1-darwin-x64.tar.xz.

############################################################################################################ 100.0% Computing checksum with shasum -a 256 Checksums matched! Now using node v16.15.1 (npm v8.11.0) After the installation is complete NVM automatically switches to the latest LTS version of Node.js that you just installed.

1. To install a specific LTS release line (a version other than the latest version), use the -lts argument along with the release line name that you want to install.
2. Nvm install -lts=argon The example command installs the “argon” LTS line of Node.js.
3. Refer to the for LTS release names.
4. To switch to the latest LTS version of Node.js that is already installed on your system, use the following command: nvm use -lts Now using node v16.15.1 (npm v8.11.0) To switch to a specific LTS version of Node.js, use the following command: nvm use lts/argon The example command switches to the “argon” LTS line of Node.js.

Now using node v4.9.1 (npm v2.15.11) Although NVM is very straightforward to use, it also provides some advanced capabilities. See the for a full list of all advanced topics.

1. NVM allows you to migrate packages from an earlier version of Node. The nvm install command can be used with the optional -reinstall-packages-from= flag to install a new version of Node with the packages from an earlier release. The following command installs the latest version of Node, but it also performs a reinstall of the packages from the default version of Node and links them. nvm install node -reinstall-packages-from=default Note Reinstalling packages does not update the NPM version.
2. NVM enables you to define custom colors to display the various Node versions and aliases. These colors are defined on the, Use the command nvm set-colors, If you add the -no-colors flag to a command, the information is displayed in black-and-white. nvm set-colors rgBcm
3. You can also specify a default Node version number within the,nvmrc file. This file can be located in the root directory or in any parent directory. The version indicated in,nvmrc is used if no version is specified on the command line.

NVM allows you to uninstall Node versions that are no longer required.

Run the command nvm uninstall with the version of Node you’d like to remove. You cannot remove a version you are currently using, so you must switch to a different version first. nvm uninstall 13.10.1 NVM confirms the Node version has been removed. Uninstalled node v13.10.1

If you no longer intend to use NVM, you can uninstall it with the unload command.

1. Deactivate NVM with the nvm deactivate command. This clears any path variables. nvm deactivate
2. Uninstall NVM. nvm unload
3. Clean up your,bashrc file by removing the following lines: export NVM_DIR=”$HOME/.nvm” && \. “$NVM_DIR/nvm.sh” # This loads nvm && \. “$NVM_DIR/bash_completion” # This loads nvm

Note If you only want to go back to using the system’s version of Node, you do not have to uninstall NVM. In this case, run the command nvm use system, You may wish to consult the following resources for additional information on this topic.

Do I have npm installed?

Checking if Node & NPM are Installed – Make sure you have Node and NPM installed by running simple commands to see what version of each is installed and to run a simple test program:

• Test Node. To see if Node is installed, open the Windows Command Prompt, Powershell or a similar command line tool, and type node -v, This should print a version number, so you’ll see something like this v0.10.35,
• Test NPM. To see if NPM is installed, type npm -v in Terminal. This should print NPM’s version number so you’ll see something like this 1.4.28
• Create a test file and run it. A simple way to test that node.js works is to create a JavaScript file: name it hello.js, and just add the code console.log(‘Node is installed!’);, To run the code simply open your command line program, navigate to the folder where you save the file and type node hello.js, This will start Node and run the code in the hello.js file. You should see the output Node is installed!,

Can you see Node.js code?

No, Nodejs code is not visible to client side. To be precise Nodejs is javascript run-time environment which means it is a engine that executes the code written in javascript on server side, where as the code which is visible runs on client side (basically browers).

How to check javascript in cmd?

Asked 5 years, 4 months ago Viewed 9k times As a total novice with JavaScript, I’m struggling to understand how to “load” my code so I can test it using unit tests outside of the application. In PHP, I have an autoloader (composer) so I can just reference the class I want to interact with and it is loaded automatically, or I can use require_once to include a physical file and the classes or functions in that file are available to me.

So, one of the classes (stored in a file src/lib/App/Calculator.js), App.Calculator = (function () ; Calculator.prototype =, calculate: function () else if (typeof this.onUpdateCallback === ‘function’) }, getAmountTendered: function (), getChange: function (), setAmountTendered: function (amountTendered), setAmountDue: function (amountDue) this.calculate(); } }; return Calculator; })(); I want to be able to create a new instance of App.Calculator and test it, outside of the application.

From the command line. Coming from PHPUnit to JS and I know I’m missing a LOT of understanding, so any pointers (opinionated or otherwise) would be appreciated. asked Jan 3, 2018 at 14:44 7 The best would be to just test your code in a browser using the F12 debug command line. Another option if you want to do it in the actual command line is to use Node.JS. This is basically a back end application for javascript and what you can do is just paste the code into a,js file, then use the CMD command: “node ” and it will run the file. Using console.log you can log to the command line. Liam 27.1k 28 gold badges 123 silver badges 187 bronze badges answered Jan 3, 2018 at 14:50 13

How to check the version of js in terminal?

Oct 2, 2020 The easiest way to check what version of Node.js you’re using is to run node -version from your terminal. This will print your version of Node.js as shown below. $ node -version v10,16,3 $ You can also get the currently running version of Node.js from Node.js’ built-in process.version property, console,log(process.version);
