Yarn: Cannot authenticate in npm registry using _authToken

[brpaz]

Hello.

I am trying to publish a package to npm registry using "yarn publish" command, from Circle CI.
I have an Auth token for the NPM registry but I am not sure how to set it in yarn.

I tried

yarn config set //registry.yarnpkg.com/:_authToken $NPM_TOKEN
yarn publish --non-interactive

But I get the following error:

error No token found and can't prompt for login when running with --non-interactive.
info Visit https://yarnpkg.com/en/docs/cli/publish for documentation about this command.

What I am missing?

Thank you.

In CircleCI you can try something like:

command: echo "//registry.yarnpkg.com/:_authToken=$NPM_TOKEN" >>~/.npmrc
