 => Errors while adding packages:             
                                              
While building package npm-container:
error: couldn't run `npm shrinkwrap`

What I'm doing

• meteor add meteorhacks:npm
• edit packages.json

{
  "ytdl-core": "0.4.1",
  "youtube-api": "0.3.2"
}

• run meteor

Another way to do it?

I'm reading the docs and they say it should be possible to include npm modules manually with
packages/ytdl-core/ + package.js

Npm.depends({
  'ytdl-core': "0.3.2"
});

But then in my app when I call on the server-side var ytdl = Npm.require('ytdl-core'); I have an error and as far as I can see that module is never being installed by meteor.

Help? 😄

Seems like the problem is the youtube-api module that is not installing

FIXED

npm cache clean -f did the trick

☺️
