My colleague recently installed Node Version Manager on his Macbook using Homebrew, and ran the two commands suggested at the end of the install script:
export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh
Everything works fine in the terminal window in which the install took place, but if he opens up a new terminal window or even a new tab, he has to install NVM all over again.
My level of command-line experience is relatively low (I don't know what I don't know), so I'm not sure where to start diagnosing the problem. Suggestions are welcome.
