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

Updating the .npmrc files' entries for scoped and un-scoped packages worked for me. So I ended up using the

npm config set @scope_name:registry SCOPED_REGISTRY_URL

and

npm config set registry PUBLIC_REGISTRY_URL

Answer 2

Try this

  Step-1) Delete package-lock.json from root folder.
  Step-2) Delete node_modules folder
  Step-3) run npm install command in root

Answer 3

My problem was 2 things:

1. Bad package-lock.json file
2. The existance of npm-shrinkwrap.json together with the package-lock.json file

What i did is:

1. Deleted the package-lock.json file
2. Delete the npm-shrinkwrap.json file
3. Ran npm install again (which recreated a good package-lock file)

Fixed my error!
