Change your registry to npm.pkg.github.com

npm ERR! code E401 npm ERR! Unable to authenticate

Are you coming across this error? hopefully, this post will help you.
The idea for writing this came when I had been given my work laptop and was supposed to set up the environment for development but I did not know that npm’s default registry is //registry.npmrc.org and not //npm.pkg,hithub.com, which is what my company uses.

I spent hours and hours trying to figure out what the issue was and did not come to any answers only bits and bobs here and there, which was not particularly useful.

Because I don’t want you to end up in the same loophole as me, you only need to follow these steps to change your registry.

  1. Open your terminal and check what registry you have.
npm get registry

if the outcome is https://npm.pkg.github.com/ you’re good to go but if its
https://registry.npmjs.org/ then stay with me.

2. To change your registry run:

npm config set registry https://npm.pkg.github.com/

npm config set registry https://npm.pkg.github.com/

3. To confirm that you’re on the correct registry run again:

npm get registry

sweet! you’ve changed your registry

4. Now you’ll probably have to log into your GitHub account, first check who’s the user by running:

npm whoami

at this point, you should get an error because you’re not logged in, but if you get a username that is not yours then run:

npm logout

5. At this point you need your GitHub account token to carry on with the following steps. If you haven’t go a personal token follow the steps here.

6. Now, to log in run:

npm login

enter your username, password (which would be your token, NOT your GitHub account password), and email.

7. If you followed these steps you should now be good to go YAY!
