Fix Npm Global Install Needs Sudo

Each time I go to set up npm I am frustrated by the errors saying that I don't have permission to npm i -g <package>, and it's frustrating. And I forget what I need to do to tell npm to install packages in a directory I own, and my shell to look there so that I can use the executables.

        
mkdir ~/.npm-global
export NPM_CONFIG_PREFIX=~/.npm-global
export PATH=$PATH:~/.npm-global/bin

For the fix to remain persistent you need to put these two lines in your shell profile like ~/.bashrc or ~/.zshrc.

        
export NPM_CONFIG_PREFIX=~/.npm-global
export PATH=$PATH:~/.npm-global/bin
