title: Installing watchman for Reach Native in Mac OS X Catalina
body: <p>I'm having trouble getting the latest version of Watchman to install property on Mac OS X Catalina.</p>
  
  <p>I am using <code>Homebrew 2.2.1</code>. I get this error when doing a clean install of <code>brew install watchman</code>.</p>
  
  <pre><code>==&gt; Pouring watchman-4.9.0_3.catalina.bottle.tar.gz
  Warning: The post-install step did not complete successfully
  You can try again using `brew postinstall watchman`
  </code></pre>
  
  <p>Running <code>brew postinstall watchman</code> just gives me the same message. If I just try to run <code>watchman</code> I get this error.</p>
  
  <pre><code>while computing sockname: failed to create /usr/local/var/run/watchman/USERNAME-state: No such file or directory
  </code></pre>
  
  <p>How do I install the latest version of watchman on Mac OS X Catalina?</p>
