Error installing create-react-app with npm

问题

When I try to install create-react-app (or nodemon) globally or even within a project, I get the following error. However, I can install other packages perfectly fine both globally and locally. I think it has something to do with the fact that both create-react-app and nodemon are run from the terminal rather than used within a project's code.

I have already tried reinstalling nodejs and opening the terminal as administrator, but that did not work.

$ npm i -D nodemon

UPDATE: When I ran npm cache clean --force, I got the following error

$ npm cache clean --force

回答1:

Run npm cache clean --force and then try installing again

回答2:

Did you try to execute the command as administrator?

回答3:

I was facing the same issue. Found a solution for the same.

Go to C:\Users\%UserName%\AppData\Roaming\npm-cache
Delete all items present there
Some files inside 1 or more folders you may not be able to delete, then just rename them to some random name.
Now retry npm install. It should work
