Resolve an npm installation issue caused by error code EINTEGRITY

After reviewing numerous similar posts on this platform, I have yet to find a solution. Many suggest using npm cache verify or npm cache clear, but these haven't worked for me.

I even took the extreme step of completely removing npm and node through various methods, including using --force. Unfortunately, nothing has resolved my issue. Below is the latest log in hopes that someone can identify where I may have gone wrong or guide me towards a potential solution.

Here is the most recent log:

Answer №1

I was able to fix the issue by executing the following commands:

rm -rf package-lock.json node_modules
npm install

Source

Answer №2

Recently faced a similar issue at my workplace too. It turned out that the package-lock.json file in our main branch was causing trouble due to outdated integrity values. The solution? Simply deleting the package-lock.json file allowed me to successfully run npm install without encountering any EINTEGRITY errors.

I stumbled upon a helpful answer on Stack Overflow regarding this exact issue: Integrity checksum failure while installing API Connect toolkit #apiconnect.

The fix was actually found in a GitHub issue comment related to npm, which can be seen here: https://github.com/npm/npm/issues/16861#issuecomment-305527498

Answer №3

In the event that this issue arises during the initialization of a react-native project, execute the following command:

npm cache clean --force

https://i.stack.imgur.com/Xz418.png

Answer №4

After removing the node_modules and package-lock.json from the solution directory, I executed npm install again which resolved the issue completely.

Answer №5

While many might suggest deleting the package-lock.json file, I believe that may not always be the best solution. Especially when working on older code with specific dependencies, removing it could cause more harm than good.

Instead, a more effective approach would be to swap out the outdated package-lock.json with one from a different branch or previous commit where things were working fine, and then proceed with running npm install.

This method worked wonders for me in resolving the issue at hand.

Answer №6

Verify the npm registry being used both locally and remotely.

I encountered an issue when I unintentionally altered the CI registry and then committed a local package-lock.json file that contained a different registry.
The discrepancy in registries definitely led to a conflict in package signatures, resulting in the problem at hand.
