Install Multiple version of node on linux
Date Posted: 08-05-2017
We want two version of node version on a single server. Alternatives is an utility which can be used to install two version of any package.
Assumption:
- Ubuntu Host
Implemntation:
Let’s start with node installation. We will use one normal apt-get to install node version and other one from source.
apt-get install nodejs
Install npm(node package manager)
apt-get install npm
After successful installation of both the package, verify the node version.
nodejs -v
Now, install different version of node. Let’s create a directory for node package on /usr/local/bin/node
mkdir /usr/local/bin/node
Change the directory and download the different version of node from official website.
cd /usr/local/bin/node
wget https://nodejs.org/dist/v5.0.0/node-v5.0.0-linux-x64.tar.gz
Extract the downloaded file.
tar -xzf node-v5.0.0-linux-x64.tar.gz
Here comes the main part, use alternatives to configure both version
update-alternatives --install "/usr/bin/node" "node" "/usr/bin/node" 100
update-alternatives --install "/usr/bin/node" "node" "/usr/local/bin/nodes/node-v5.0.0-linux-x64/bin/node" 50
To switch the version of node, use the following command.
update-alternatives --config node
Select 2 to change version to use node-v5 version in this example.
Similarly, use the below commands to configure two different version.
update-alternatives --install "/usr/bin/npm" "npm" "/usr/bin/npm" 100
update-alternatives --install "/usr/bin/npm" "npm" "/usr/local/bin/nodes/node-v5.0.0-linux-x64/bin/npm" 50
To switch the version of npm,
update-alternatives --config npm
