I am trying to install NVM as per these instructions
I typed in this command in terminal:
$ curl https://raw.github.com/creationix/nvm/master/instal
I had fixed this problem.
export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
