Answer 1

Had this exact issue on an existing Angular 10 project. The following steps resolved the issue for me:

1. Delete the package-lock.json file.
2. Delete the node_modules folder and all of its contents.
3. Run npm install. Note that in my case I had to add the --force flag. YMMV

At this point, ng build --prod completed successfully for me.
