ERROR in [default] \node_modules\angular2-logger\app\core\logger.ts:62:38 Type 'string' is not assignable to type 'Level'.

This problem appeared with angular2-logger 0.3.0 after I updated to Angular 2 rc5. I just updated angular2-logger to its latest 0.4.2 and the problem still shows up.

ERROR in [default] \node_modules\angular2-logger\app\core\logger.ts:62:38 Type 'string' is not assignable to type 'Level'.

Changing the line from:

private _loadLevel = (): Level => localStorage.getItem( this._storeAs );

to

private _loadLevel = (): any=> localStorage.getItem( this._storeAs );

seems to resolve the problem.

Ha, edited the best part 😃 Most heated “search for truth” I’ve witnessed so far! Thanks guys!

Yea @ascreamingweas ,

In short, it means your build process is compiling this third party library which is an overhead in your build process since the library is already compiled, the fact that you get this error means your build process can be highly improved in order to avoid already compiled third parties (not only this one, but any), getting compiled once again by your PC. If you follow the Quickstart Guide in Angular 2 for either SystemJS or Webpack you won’t get this error.

If you don’t care about this extra overhead in your project’s build process you can leave it as is, I’ll be commiting a fix for this error soon enough.
