I keep having this problem so I uninstalled homebrew and tried to uninstall npm, but it did not work. I installed homebrew again and then typed "brew install npm." It returned "Warning: node-0.12.7 already installed." I then tried to use npm with the following command: "npm install -g mup" and it returned "-bash: npm: command not found."
I have trouble uninstalling npm because on the site it uses npm to uninstall npm... Otherwise, it denies me permission. How can I get around this so that I can install mup with "npm install -g mup"? What's weird is that it was working earlier but now it is failing me. Thank you.
Try this
cd ~
sudo rm -rf .npm
brew update
brew uninstall npm
brew install npm
