"npm install" Problem After Code Developers Added Utility Modules

[JPJen]

After our code development team added some utility modules, there are errors when we run "npm install" on our project.

We found a solution if we use the Virtual Machine -- go to the /home/dev/ directory, delete the ".npm" folder, then, we are able to run "npm install" successfully.

But, we are still unable to run "npm install" in the Windows 7 environment.  I am writing to find out if anybody knows what to do in the Windows 7 environment.  Thank you very much.
