NPM install hangs on loadRequestedDeps

Question

When I download any package using NPM, it hangs on the last command "loadRequestedDeps." I've added my whole -verbose output to the end of this question for reference. It will just sit there until I cancel the command, and nothing will be installed and my package.json will not be updated.

What could the issue be? I've looked around but haven't found out how to fix my particular problem.

Here's some info:

• OS is Windows 10
• Node version is 6.9.1
• NPM version is 3.10.8
• My CPU maxes out at 100% whenever I run NPM install. Could that be the issue itself? I used to be able to use NPM install on this computer, however.

Thanks for anyone who can help. The verbose output is below.

I had this exact same issue, and it drove me crazy for about a day before I found these solutions.

After creating a new "tmp" folder in my C drive, and then changing the TEMP variable in my SYSTEM Environment variables to C:\tmp. My "npm install" was still not working. (This action was based on Zach Nagatani's answer.)

I also had two TEMP variables defined in my USER Environment variables, and I had to delete one of the variables for my "npm install" to start working.

The above action was based on this post: https://github.com/npm/npm/issues/7590

I was so glad when I found it. Many thanks to you all.
