title: Rails Error Can't Find freedesktop.org.xml
body: <p>I've had some issues starting a new RAILS project, where I'm getting an error that there is a missing file <code>/usr/local/share/mime/packages/freedesktop.org.xml</code>. There was a connection with the mimemagic dependencies, and I found this issue on GitHub about the mimemagic version and licensing - <a href="https://github.com/rails/rails/issues/41750" rel="noreferrer">https://github.com/rails/rails/issues/41750</a></p>
  <p>Wondering if anybody else ran into the issue, and could explain what is going on.</p>
  <p>I'm using rbenv with ruby version: 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-darwin19], and rails 6.1.3</p>
  <p>Here is the error message in the command line:</p>
  <pre><code>Installing railties 6.1.3

  Ensure you have either installed the shared-mime-types package for your distribution, or 
  obtain a version of freedesktop.org.xml and set FREEDESKTOP_MIME_TYPES_PATH to the location of that file.
