I take it that you have "Hello World" as the "name" field in your package.json? Capital letters and spaces are not allows in the "name" field of package.json.

hey we're sorry to hear you're having another problem, but can you please post that one in a new github ticket? this way it'll be easier for us (the issue triagers) to keep all the issues sorted, and in turn help you better 😄

[smikes]

Is this still a problem for you?

This looks like you lack the necessary permissions to write to your npm cache. You can fix this like this:

chown -R yuchen ~/.npm

We are trying to clean up older npm issues, so if we don't hear back from you within a week, we will close this issue. (Don't worry -- you can always come back again and open a new issue!)

Thanks!

Closing as resolved.
