javascript - How to uninstall the previous version of npm and install the new version?

Question

I used npm uninstall and npm remove respectively and found that they could not be successfully uninstalled

Answer 1

Delete node_modules first, but it is recommended not to delete it manually as it may be slow. You can
npm install rimraf -g
rimraf node_modules

Then perform npm uninstall operation

Answer 2

npm uninstall xxx --save

Answer 3

No need to uninstall, npm install -g npm

Answer 4

The reason why it cannot be deleted is that this module depends on vue-loader, so it cannot be uninstalled.
I solved the problem by deleting the entire node-modules folder and reinstalling it
