Invalid rule result: Instance of class Promise

Question

I work with Angular 7.1.4. I want to generate a new module with the following line;

ng g m order-process

But I encountered an error:

Invalid rule result: Instance of class Promise.

How to fix this? Node: 8.11.3

Answer 1

I'd solved my problem. My angular/cli version is 7.0.7 but I was find the @schematics/angular@8.0.3 in package-lock.json. So, I run the "npm install @schematics/angular@7.0.7 --save-dev" command and solved my problem. Thank you for interested.
