When I run `npm install`, it returns with `ERR! code EINTEGRITY` (npm 5.3.0)

Question

I am getting this error while running sudo npm install. On my server, npm was installed earlier. I\'ve tried to delete the package-lock.json file,

Answer 1

There are several valid and helpful responses here, but I would like to add that in my case the simplest solution was:

1. Delete package-lock.json;
2. Remove folder AppData\Local\npm\cache or AppData\Roaming\npm\cache;
3. Remove folder node_modules.staging;
4. Run npm install again.

After that everything ran smoothly.
