# Resolving EACCES permissions errors when installing packages globally
# https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally

On the command line, in your home directory, create a directory for global installations:

    mkdir ~/.npm-global

Configure npm to use the new directory path:

    npm config set prefix '~/.npm-global'

    npm config list

In your preferred text editor, open or create a ~/.profile file and add this line:

    echo "export PATH=~/.npm-global/bin:$PATH" >> ~/.profile

    cat ~/.profile

On the command line, update your system variables:

    source ~/.profile

To test your new configuration, install a package globally without using sudo
