Have you tried updating npm as @StephenGrider suggests? https://nodejs.org/en/download/

Looks like you may have installed on E drive, the documents instruct you to:

"Next, make sure that your project files are on the C drive rather than on some external or remote drive. This may be causing permissions errors or inconsistencies with the install.".

I had the same issue.

I had the same error even with everything installed in the C drive. I had to run npm cache clear --force to get it to work.

Hi there,

I also faced the same problem. Turns out, if you have done npm start and running the app in localhost, then it is throwing this error. Try terminating the localhost instance once and then run npm install. It worked for me.
