NPM install hangs when installing packages

I currently using a project. It works fine but the problem when I remove the project files(except node_modules) to another folder or GitHub, reinstalling packages via npm is not successful. It always hangs at

extract:rxjs: sill extract [email protected]

I tried npm cache verify no luck.

Here is packages.json

  }
}

I am using:

• Windows 10
• Node version: 8.50

Any ideas what is wrong? Kind Regards

Solved problem by

1. Remove package-lock.json
2. Remove node_modules folder
3. Run npm install again. (took 30 minutes to finish but finally did)
