[itsJess1ca]

Please provide us with the following information:

1. OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
   Windows 10
2. Versions. Please run ng --version. If there's nothing outputted, please run
   in a Terminal: node --version and paste the result here:
   local (v1.0.0-beta.10, branch: master)
3. Repro steps. Was this an app that wasn't created using the CLI? What change did you
   do on your code? etc.

• App created with webpack cli built from master.
• Ran npm install lodash --save,
• imported lodash into my component with import * as _ from 'lodash';
• proceeded to use lodash functions (_.forIn() in this case)

1. The log given by the failure. Normally this include a stack trace and some
   more information.
   Cannot find module 'lodash' .
2. Mention any other details that might be useful.
   I haven't noticed this with other libs I'm using, including material2 and ngrx/store.

Thanks! We'll be in touch soon.

I had better luck with "@types/lodash": "^4.0.26-alpha" and using the same import.

Ok so installing @types/lodash as well resolved the issue - though If possible a better error message would be nice here.

Something like Couldn't find types for module 'lodash'

Same here. I have created a custom type definition for a 3rd party library and then the error was gone. The error message is not clear.
