• How did you install nvm? (e.g. install script in readme, Homebrew):

  Git install (but using Install & Update script leads to the same)

• What steps did you perform?

nvm install node

• What happened?

nvm is not compatible with the npm config "prefix" option: currently set to "/var/home/logol/.nvm/versions/node/v11.14.0"
Run `nvm use --delete-prefix v11.14.0 --silent` to unset it.

• What did you expect to happen?
  nvm should not think there is a prefix set

• Is there anything in any of your profile files (.bashrc, .bash_profile, .zshrc, etc) that modifies the PATH?

# .bashrc

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" 
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

Is your $HOME dir a symlink, or mounted from elsewhere?

[john-gold]

yes, the $HOME is a symlink to var/home

[ljharb]

That’s the problem - nvm doesn’t support a symlink as the home or nvm dir. See #617.

[john-gold]

okay thanks for the information, should have done a deeper research (will go for the temporary solution mentioned in your reference)
