[BUG] Automatic authentification on private npm repository no longer works #2935
Description
Current Behavior:
We use a private nexus repository with an .npmrc file on each project.
Our .npmrc looks like (URL changed for this bug report):
registry=https://our-url.example.com/repository/npm/
_auth=${NEXUS_TOKEN_ENV_VAR}Since the npm v7.7.0 release we have the following error when we do an npm install in our projects:
npm ERR! code E401
npm ERR! Unable to authenticate, need: BASIC realm="Sonatype Nexus Repository Manager"
This configuration always worked previously (npm v6 & npm < v7.7.0)
Note: doing a npm adduser allow us to install our package in our dev local env.
It create a $HOME/.npmrc file with what's seems to be an undocumented format.
But this is not usable when doing automatic build with Jenkins / docker, since it prompt user for information.
Expected Behavior:
npm install works as expected.
Steps To Reproduce:
Configure a private repository with basics HTTP auth, and use it with a specific .npmrc in the project, like explain above.
