Angular quickstart error

I'm trying to run tutorials from angular.io. I'm getting an error on npm start. Here is the error. I tried to uninstal all npm, typescript, node, angular. First part of the error:

npm WARN invalid config loglevel="notice"

    npm ERR! Exit status 2

    npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
