In my case we had an old package-lock.json that caused these issues. Regenerating package-lock.json fixed the issue. To do this delete package-lock.json and then run npm install

One of the packages was deprecated. I started in new folder a test project and then copied some of the packages to this tested project until found the problematic package.

create on new folder a test-project and open cmd in this location.

npm init -y // creates package.json with defaults copy to depencencies / devdependencies in that package.json packeges from the origin project. npm i

It seems that running

npm cache clear --force

Is what worked and recommended by everyone. Unfortunately, it did not work for me. There were other suggestions to save-dev first. This also did not work for me.

What I did in order to overcome this issue myself, was narrowing my package.json dependencies. I removed all of them, and kept returning them incrementally until I found the dependency that was causing the issue. I updated the dependency version, and this was what I needed to overcome this issue.

My problem was because the wifi adaptor of my PC was very inconsistent and would give network errors often, giving the error mentioned, among others, when trying to install bigger packages (in my case, expo). What helped in my case was tethering my android phone to PC and using the connection that way.

For me, the error came up while I was trying to work with the json-server module. And clearing the cache worked for me

npm cache clear --force

Afterwards, reinstall/update your mode modules

npm install

If that doesn't work, try reseting you npm config:

npm config set registry https://registry.npmjs.org/

Solution 1: Cache Clear

First, run this command:- npm cache clear --force

Then run this command:- npm install

Solution 2: set npm config

You need to set npm config registry just like this.

npm config set registry https://registry.npmjs.org/

We can also run npm install with registry options for multiple custom registry URLs.

npm install --registry=https://registry.npmjs.org/
npm install --registry=https://custom.npm.registry.com/

If you are using the latest node version, just force to clean cache. command:

npm cache clear --force
