I get an error when running npm install.
The error is:
npm ERR! Cannot read property 'pickAlgorithm' of null
npm ERR! A complete log of this run can be found in:
npm ERR! npm-cache\_logs\2021-10-14T08_03_47_266Z-debug.log
I did the following but the error stays:
node-modulesnpm cache clear --forceEnvironment:
OS: Windows 10
react native: 0.65.1
Node: 14.17.4
npm: 7.21.0
please use following:
npm cache clear --force
npm install
in my case it is working
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/
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.
Running this worked for me
npm config set registry https://registry.npmjs.org/
Upgraded to npm v7.23.0 and then npm install so it's working fine now.
if you are using Windows OS, close VS Code then open command prompt as administrator and run npm cache verify and npm install
it works for me
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
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/
First run npm cache clear --force and then close VPN. It worked for me (in China)
If these solutions didn't work,
npm cache clear --force
npm install
Then this will definitely work!
npm config set registry https://registry.npmjs.org/
After executing the above command,
npm install --legacy-peer-deps
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
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.
