I’m using PM2 for managing all the server processes. So, installing node and nvm (node version manager) is now one of the first things I do during an application server setup.
node and nvm, just like ruby and rvm (ruby version manager) are always installed under the non-root user account.
install nvm
nvm can be installed by using wget or curl
using wget
$> wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
using curl
$> curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
Running either of the above commands downloads a script and runs it. The script clones the nvm repository to ~/.nvm, and attempts to add the source lines from the snippet below to the correct profile file.
~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc
The script that gets added is
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
After this, we either need to restart the current shell or by
$> source ~/.bashrc
install node
To list the node versions available for install
nvm ls-remote
To install a specific version
$> nvm install 16.10.0
To see the current list of installed node versions
$> nvm ls
And to use a specific version
$> nvm use 16.10
set a node version as default
When nvm is installed, it generates a .nvmrc file in the home directory. The default version of node to be used can be entered there.
$> cat ~/.nvmrc 16.10
