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

SherylHohman's answer solved the issue I had, but only after I switched my internet connection. Intitially, I was on the hard-line connection at work, and I switched to the WiFi connection at work, but that still didn't work.

As a last resort, I switched my WiFi to a pocket-WiFi, and running the following worked well:

npm cache verify

npm install -g create-react-app

create-react-app app-name

Hope this helps others.
