Prepare environment

Install nvm and Node

Change to users home and create users’s profile .bash_profile (if not exist)

cd $HOME
touch .bash_profile

Download nvm install script and run it. The installation script also modifies the users’s profile .bash_profile

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

Run users’s profile, so nvm will be installed. This ist done automatically after login.

. .bash_profile

Install latest Node LTS version

# install latest version
nvm install node --reinstall-packages-from=node

# install a specific version
npm -install 8.12.0

# set nvm aliases (used in direnv configuration)

nvm alias default 8.12.0

# install additional packages
