Getting authentication error when running yarn install

[alvincrespo]

What is the current behavior?

I'm currently using ember-cli to install a package:

ember install ember-cli-mocha

While running this command, I get the following:

➜  ember-links-with-follower git:(ac-upgrade) ember install ember-cli-mocha

My yarn-error.log is here.

I'm having the same issue https://github.com/yarnpkg/yarn/issues/3093, would be good to get these triaged together? There seems to be something specifically wrong with fetching packages from @glimmer?

This also seems to be related: https://github.com/yarnpkg/yarn/issues/3407

For anyone else who runs into this, based on #3407 I've managed to figure out a workaround, by commenting several lines of my ~/.npmrc file.
