title: Installing packages from github npm registry - auth error 401
body: <p>I have just published a private package on GitHub, trying to figure out how it should be working. now I'm trying to install it in another project. I authenticated with <code>npm login --registry=https://npm.pkg.github.com</code> with an access token that has <code>write:packages</code>, <code>read:packages</code> and <code>repo</code> privileges. While trying to run <code>npm install https://npm.pkg.github.com/@orgname/package-name</code> I get an error message:</p>
  
  <pre><code>npm ERR! code E401
  npm ERR! Unable to authenticate, need: Basic realm="GitHub Package Registry"
  </code></pre>
  
  <p>How can I add/get this privilege? </p>
