For anyone with this issue in the future. It seems I had another, old version of npm in my Users/myname/ folder, which was being utilized instead of the global, current npm version.

The error posted points to npm being very out of date, there may be something wrong with what version is being used. If you use tools like nvm make sure those are functioning properly.
