Description

I set up 2 new Angular-Projects and set them up EXACTLY like in this tutorial: https://medium.com/@nikolasleblanc/building-an-angular-4-component-library-with-the-angular-cli-and-ng-packagr-53b2ade0701e . Every time i try to run the ng-packagr it fails and then there is the following error:

npm run forestrun

bte@0.0.0 forestrun C:\Users\Kevin.DeGoede\Documents\yoyo\bte ng-packagr -p ng-package.json

When trying again the following error will occur:

When I try to access the dist/src folder with the system explorer I cant access it since I am not permitted to access it, although being logged in as the user it requests.

How To Reproduce

You can follow the tutorial https://medium.com/@nikolasleblanc/building-an-angular-4-component-library-with-the-angular-cli-and-ng-packagr-53b2ade0701e on Windows 10 with the Angular IDE.

I dont know whether there is something wrong with my OS or with the other software I am using. I tried it on another PC with another Windows 10 Build, but the error will still occur there. I also tested the same on a Mac and it worked fine.

Expected Behaviour

The behavior I expected was that packing the application works fine, just like on my Mac.

In case anyone else stumbles upon this for a similar reason:

I started getting this in angular-cli 6 when doing ng build my-lib --prod: I needed to add this to my tsconfig to resolve it:

“exclude”: [“dist”]

@markwhitfeld In case you’ve installed the VSCode plugin “Angular Language Service”, try to deactivate it. It locks files and prevents ng-packagr from working correctly.
