Getting error on npm install as npm ERR cb() never called

Question

I have set a proxy in npm global config. On installing any package I am getting following error. Below is my node and npm version: npm: 6.13.4 node: v12.16.1

As I am behind proxy, what else is required to overcome this issue. Every help will be appreciated. I have also tried by updating node version, removing and after restart setting proxy again, but none of that worked.

    C:\test>npm i level-db-helper
    npm ERR! cb() never called!

    npm ERR! This is an error with npm itself. Please report this error at:

Answer 1

Finally I found the culprit of this issue by my own research, It was due to inaccessible proxy url, so after changing the npm proxy and https-proxy by following command I resolved this issue.

(You need administrative rights to execute this command)

npm config set proxy http://your-proxy-url.com:PORT_NUMBER
npm config set https-proxy http://your-proxy-url.com:PORT_NUMBER

Answer 2

I got the same error when, npm install from docker. deleted the un-used docker images, using the following commands

docker image prune
docker image rm <imageId>

It solved the issue for me

One of the reasons for this issue is that you have package-lock.json file in your project directory. So, you may have to delete or rename the package-lock.json file from the directory and then run the npm install command. Best option is to delete this file.

Hope it will work for you.
