title: but these conflict with your requirements or minimum-stability
body: <p>I am creating my own slackbot. I decided to use project as a library to help me.</p>
  <p><a href="https://github.com/sagebind/slack-client/issues?utf8=%E2%9C%93&amp;q=stability" rel="noreferrer">https://github.com/sagebind/slack-client/issues?utf8=%E2%9C%93&amp;q=stability</a></p>
  <p>Now I need to install it with composer.</p>
  <p>So I used the command: <code>composer require coderstephen/slack-client</code></p>
  <p>...And I get the error:</p>
  <pre><code> Problem 1
      - Installation request for coderstephen/slack-client ^0.3.0 -&gt; satisfiable by coderstephen/slack-client[v0.3.0].
      - coderstephen/slack-client v0.3.0 requires devristo/phpws dev-master -&gt; satisfiable by devristo/phpws[dev-master] but these conflict with your requirements or minimum-stability.
  </code></pre>
  <p>Ok - So then I decided to change my stability level to &quot;dev&quot; in my <code>composer.lock</code>:</p>
  <pre><code>&quot;aliases&quot;: [],
      &quot;minimum-stability&quot;: &quot;dev&quot;,
      &quot;stability-flags&quot;: {
          &quot;devristo/phpws&quot;: 20
      },
      &quot;prefer-stable&quot;: true,
      &quot;prefer-lowest&quot;: false,
      &quot;platform&quot;: {
          &quot;php&quot;: &quot;&gt;=5.5&quot;
      },
      &quot;platform-dev&quot;: []
  </code></pre>
  <p>Now I'm running out of ideas on what to do. The README says to do this step in composer.json but, no such settings exist:</p>
  <blockquote>
  <p>Please note that the current version has unstable dependencies.</p>
  <p>In order to install those dependencies, you can set &quot;minimum-stability&quot; in your composer.json, and recommend that you set &quot;prefer-stable&quot;:</p>

  <p>My composer.json:</p>

  <p>Does anyone know some solutions I could try?</p>
