[Vuejs]-Vue-socket.io install failing, cannot find 'package.tgz'

This ENOENT ... vue-socket.io/.../package.tgz error and vue-socket.io is a recurrent problem on old NPM versions.

Solution: Update your NPM version.

Considering it is a fresh install, if this doesn’t work, I’d open an issue in their issue tracker. Could be a bug (though generally unlikely).
