Desired behavior

successful compile and build

Mention any other details that might be useful (optional)

I have not uninstalled rxjs-compat, because I have some third party dependencies that use the old version of rxjs.

This appears to be a bug but we will need to look at a reproduction to find and fix the problem. Can you setup a minimal reproduction please?

You can read here why this is needed. A good way to make a minimal reproduction is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

HI,

I have had created repo-app but unfortunately, I don't get the same error. As I said earlier this is a medium application intend to be large very soon. I will try to roll back the application and try everything from begin, again. The major problem is error message: ERROR in EPERM: operation not permitted, stat 'D:\System Volume Information' - it does not mean anything to me, is not descriptive.
