[whackage] Package my-library is not a registered dependency in my-app

[ghost]

Hello! I'm trying repeat it: https://formidable.com/blog/2016/12/01/introducing-whackage/

$ whack link ../../my-library here is error: [whackage] Package my-library is not a registered dependency in my-app

After added in dependency I have new error:

`events.js:167
      throw er; // Unhandled 'error' event
      ^

Error: spawn npm ENOENT
    at Process.ChildProcess._handle.onexit (internal/child_process.js:229:19)

I ran into the same issue, ended up manually adding it in whackage.json
