Me encuentro con el siguiente error cuando intento instalar mimemagic 0.3.10 en un proyecto de Ruby on Rails. Tenga en cuenta que se ejecuta en un entorno Windows. Aquí está el seguimiento de la pila de errores más relevante:

 Fetching mimemagic 0.3.10 Installing mimemagic 0.3.10 with native extensions Gem::Ext::BuildError: ERROR: Failed to build gem native extension. current directory: C:/Ruby26/lib/ruby/gems/2.6.0/gems/mimemagic-0.3.10/ext/mimemagic C:/Ruby26/bin/ruby.exe -rrubygems C:/Ruby26/lib/ruby/gems/2.6.0/gems/rake-13.0.6/exe/rake RUBYARCHDIR\=C:/Ruby26/lib/ruby/gems/2.6.0/extensions/x86-mingw32/2.6.0/mimemagic-0.3.10 RUBYLIBDIR\=C:/Ruby26/lib/ruby/gems/2.6.0/extensions/x86-mingw32/2.6.0/mimemagic-0.3.10 rake aborted! Could not find MIME type database in the following locations: ["/usr/local/share/mime/packages/freedesktop.org.xml", "/opt/homebrew/share/mime/packages/freedesktop.org.xml", "/opt/local/share/mime/packages/freedesktop.org.xml", "/usr/share/mime/packages/freedesktop.org.xml"] Ensure you have either installed the shared-mime-info package for your distribution, or obtain a version of freedesktop.org.xml and set FREEDESKTOP_MIME_TYPES_PATH to the location of that file. This gem might be installed as a dependency of some bigger package, such as rails, activestorage, axlsx or cucumber. While most of these packages use the functionality of this gem, some gems have included this gem by accident. Set USE_FREEDESKTOP_PLACEHOLDER=true if you are certain that you do not need this gem, and wish to skip the inclusion of freedesktop.org.xml.

Tenga en cuenta que estoy respondiendo esta pregunta yo mismo, ya que encontré una solución y quiero compartirla con cualquier otra persona que pueda tener el mismo problema.
