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.

Answer 1

this is very general error .. you have to debug with

npm install -verbose

it maybe 1) locked package.json 2) you are in private network and can't access outside world for some reason 3) cache is not good ( you may try with npm clear cache ) or ( cache verify ) or even changing its path (npm config set tmp )

Answer 2

Create new folder tmp in C: drive and go to the command prompt and type:

npm config set tmp C:/tmp
