title: Repeatedly having to install xcode for git
body: <p>Whenever I try to run <code>git init</code> I keep getting the error</p>
  <pre><code>xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
  </code></pre>
  <p>I can fix this by running</p>
  <p><code>xcode-select --install</code></p>
  <p>However next time I come to making a new git repo, I get the same error and have to run the command again. Is there someway I can persist this so I dont have to reinstall xcode everytime</p>
