npm error E401: Unable to authenticate, need: BASIC realm=“Sonatype Nexus Repository Manager”

问题

I upgraded node version to 12.16.2 and npm version to 6.14.4. After that I am not able to run npm install, as I'm getting this error

 code E401
 npm ERR! Unable to authenticate, need: BASIC realm="Sonatype Nexus Repository Manager"

I even tried deleting node_modules and package-lock.json and running npm install again, but doesn't change anything.

回答1:

I found a way out. With this new npm version they are enforcing authentication to access certain packages. We realised we don't need to use authentication for any of the packages we were downloading, hence the auth code we had was unnecessary. So we just removed it and it all worked.
