Vue-Cli won't install

Issue

I have node 11.2.0

Keep receiving this error.

Solution

You are facing the problem of file permissions.

-g parameter of npm means “globally”, which will install those file in the system directory, specifically in your computer /usr/local/lib/node_modules, where the owner is possibly root and with permission rwxr-xr-x, means those who is not root will have no permission to write.

Then, you may use sudo to get this permission, or just like NPM modules won't install globally without sudo said, set the npm prefix into the path where you have permissions:

$ npm config set prefix '~/.npm-packages'
