How to install package with local path by Yarn? It couldn't find package
<p>In my <code>package.json</code> I'm pointing local package <code>my-custom-i18n</code> by its relative path:</p>
<h3>package.json</h3>
<pre><code>&quot;dependencies&quot;: {
 &quot;core-js&quot;: &quot;^2.4.1&quot;,
 &quot;my-custom-i18n&quot;: &quot;./../MyProject.Shared/myproject-i18n&quot;,
 &quot;rxjs&quot;: &quot;5.0.0-beta.12&quot;,
 ...
}
</code></pre>
<p><code>npm install</code> installs packages correctly, but <code>yarn</code> has problem with it and simply cannot find this package:</p>
<h3>yarn output</h3>
<pre><code>$ yarn
yarn install v0.15.1
info No lockfile found.

error Couldn't find package &quot;myproject-i18n&quot; on the &quot;npm&quot; registry.

</code></pre>
<p>I see that it looks it on the <code>npm</code> registry, where this package doesn't live.</p>
<h3>Question</h3>
<p>Is there any change to use yarn with local packages?
By local packages I mean packages pointed by relative path as <code>my-custom-i18n</code>.</p>
