Installing Multiple Versions Of NodeJs Versions On Your Linux System

Today, I'm going to show you how to install and manage multiple versions of NodeJs on your linux system.

We are going to use NVM to install and manage multiple versions of NodeJs on same system. So we need to install NVM first.. To install it just copy paste the below command.

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

The above script will download and install NVM on your Linux box.. Now run the below command to activate it in current terminal session or just close and open your current terminal session.

source ~/.bashrc

Now just check the NVM installation with following command..

nvm --version

It should print version like one shown below..

shivaraj@shivaraj-A14RM0E:~/articles-now$ nvm --version 0.33.8 shivaraj@shivaraj-A14RM0E:~/articles-now$

Installing NodeJs with NVM

Now we are going to see how to install the latest version of Nodejs using NVM..
Just Run the below command to install latest version of nodejs in your system

nvm install node

This will produce output like one shown below.. on successful installation..

shivaraj@shivaraj-A14RM0E:~/articles-now$ nvm install node Downloading and installing node v10.5.0... Downloading https://nodejs.org/dist/v10.5.0/node-v10.5.0-linux-x64.tar.xz... ######################################################################## 100.0% Computing checksum with sha256sum Checksums matched! Now using node v10.5.0 (npm v6.1.0)

You can check the version of node installed with node -v and npm with npm -v

shivaraj@shivaraj-A14RM0E:~/articles-now$ node -v v10.5.0 shivaraj@shivaraj-A14RM0E:~/articles-now$ npm -v 6.1.0 shivaraj@shivaraj-A14RM0E:~/articles-now$

You can install particular version of NodeJs with npm install version-number. For example to install NodeJs version 8 you can use nvm install 8

shivaraj@shivaraj-A14RM0E:~/articles-now$ nvm install 8 Downloading and installing node v8.11.3... Downloading https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-x64.tar.xz... ######################################################################## 100.0% Computing checksum with sha256sum Checksums matched! Now using node v8.11.3 (npm v5.6.0) shivaraj@shivaraj-A14RM0E:~/articles-now$

To check the different versions of NodeJs installed in your local system.. run the following command

nvm ls

shivaraj@shivaraj-A14RM0E:~/articles-now$ nvm ls v8.9.4 -> v8.11.3 v9.4.0 v10.5.0 default -> 8 (-> v8.11.3) node -> stable (-> v10.5.0) (default) stable -> 10.5 (-> v10.5.0) (default) iojs -> N/A (default) lts/* -> lts/carbon (-> v8.11.3) lts/argon -> v4.9.1 (-> N/A) lts/boron -> v6.14.3 (-> N/A) lts/carbon -> v8.11.3 shivaraj@shivaraj-A14RM0E:~/articles-now$

To switch from one version to other you can use following command.. nvm use version number. for example to use Node Version 10 you have to run nvm use 10

shivaraj@shivaraj-A14RM0E:~/articles-now$ nvm use 10 Now using node v10.5.0 (npm v6.1.0) shivaraj@shivaraj-A14RM0E:~/articles-now$

If you want to set some node version as default version to use ... you can set it with following command.. nvm alias default node-version.. if you want to set the node version 8 as default one you can set it by running this command nvm alias default 8

shivaraj@shivaraj-A14RM0E:~/articles-now$ nvm alias default 8 default -> 8 (-> v8.11.3) shivaraj@shivaraj-A14RM0E:~/articles-now$
