How to debug 'npm ERR! 403 In most cases, you or one of your dependencies are requesting a package version that is forbidden by your security policy.'

Solution 1:

If you are like me and following the Node Cookbook example, or some other example where you just made your account, your error is probably like mine.

I hadn't verified my email address and got the same error (it was a new account). Once I verified, it worked (even on VPN).

Check your email and verify your account.

Solution 2:

I got the same error while publishing to JFrog Artifactory. It was the result of already having a package with the same name in the repository. In order to fix this, either delete the old package or change the version/name of the new one.

Solution 3:

This is mainly occur in two scenearios

1. The error may result due to a *conflicting package that is public. Just change the name of the package in the package.json and try again!

2. You may have signed up recently and forgot to verify the email. So, you can login to this link: https://www.npmjs.com/login

   On the header you will see an option to send a verification link to your email. Once you complete the verification, try to publish it again.

Remark: 2) worked for me.
