title: How to install local package with Yarn v3?
body: <p>I bashed my head against the wall trying to install a local package using Yarn v3. Here all the things I tried:</p>
  <ol>
  <li>Run <code>yarn add file:../hardhat-packager</code></li>
  <li>Run <code>yarn add ../hardhat-packager</code></li>
  <li>Manually add <code>&quot;hardhat-packager&quot;: &quot;file:../hardhat-packager&quot;</code> in <code>package.json</code></li>
  <li>Manually add <code>&quot;hardhat-packager&quot;: &quot;../hardhat-packager&quot;</code> in <code>package.json</code></li>
  </ol>
  <p>All of the above resulted in Yarn getting stuck at the installation step, as shown in the screenshot below. I waited more than five minutes and I made sure that my Internet connection is fast.</p>
  <p>I know that there is an option to <a href="https://yarnpkg.com/cli/link" rel="nofollow noreferrer">link</a> a package, but that is not quite white I want. I don't want symlinks, I want the actual package files copied over.</p>
  <p>How can I do this? I'm using Yarn v3.2.0</p>
