Answer 4

I was also having this problem. Mine has arised because I have changed my password in npmjs.org. So, try Login in npm from terminal again with your new password and then install any module. It worked for me.

Answer 5

I had a an odd issue where I got the credentials error and it was because npm login had cached bad credentials and then npm logout didn't clear the credentials (as evidenced by "npm login" always showing my default details).

NPM stores your login under the globals NPM_CONFIG_EMAIL and NPM_CONFIG__AUTH. If you do "npm config ls -la" and see email under "environment configs" you may have the same issue I had (where npm logout didn't work).

Unset the globals NPM_CONFIG__AUTH and NPM_CONFIG_EMAIL and then npm login again and it should work. (in terminal it's just "unset NPM_CONFIG__AUTH")

Answer 6

If you have changed your system LAN password, run npm login and provide your new password.

Once the login is successful, you will not get error while doing npm install.
