Fixes for "npm ERR cb() never called" error.
To fix the npm err cd() error, i found this four solutions and it fixes my issue.
Solution 1: Clearing the NPM Cache
If the error occurs in local machine then clearing the cache fix the error.
So, first delete the package-lock.json
file and then run the following command
npm cache clean --force
and run npm install
again to update the package-lock.json file
Solution 2: Upgrade npm version
If you are running on a npm version which is lower than what is required by the package you will get the error.
To upgrade your node version globally , run:
npm install [email protected] -g
Soultion 3: Delete and Install node_modules folder
Delete package-lock.json
file and whole node_modules
folder and then reinstall everything by running the command:
npm install
Note: Do not delete the package.json file or
npm install
wont work.
Solution 4: Install the required node version
Sometimes when deploying our application on some online platform like heroku etc, we might get this error. It's because they need a specific node version to work properly.
To fix we just need to specify the specific version in the package.json
file.
"engines": {
"node": "12.x.x"
}
Once you have update your package.json file with correct version, you can deploy it.
I hope the above two solution works for you too. 😀
