Fix a npm install failure with error code EINTEGRITY

Question

I have browsed through various similar posts here to no avail. They all arrive at similar solutions about using npm cache verify or npm cache clear, etc.

I have even went as far as to completely remove npm and node using every possible method and start fresh. I even resorted to using --force. Nothing has worked. I am sharing the latest log in hopes someone can point out my oversite or at least direct me to a possible solution.

I am sharing the latest log below.

Answer 1

I just experienced this issue as well at work. The cause was that the package-lock.json file in our master branch was outdated, containing old integrity values. By deleting the package-lock.json file, I was able to run npm install and had no more EINTEGRITY errors.

I found the answer to this problem in another SO post: Integrity checksum failure while installing API Connect toolkit #apiconnect.

They came up with the answer via this GitHub issue comment for npm: https://github.com/npm/npm/issues/16861#issuecomment-305527498

Answer 2

Running these commands solved my problem:

rm -rf package-lock.json node_modules
npm install

Reference

Answer 3

If this error occurs during the project creation in react-native, then run:

npm cache clean --force
