I wanted to install ruby on rails for windows 10, following the same instructions of this video: https://www.youtube.com/watch?v=G-B_KUFNkQQ

When it finish the installation of ruby, I return to the console and after gem install rails, I get this error:

C:UsersUsuario>gem install rails --no-document
Temporarily enhancing PATH for MSYS/MINGW...
Building native extensions. This could take a while...
ERROR:  Error installing rails:

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.

I tried to solve making an update and "gem install mime-types-data" but stills with the same problem...

The Ruby Installer is Ruby+Devkit 2.7.2-1 (x64) and my ruby version is ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x64-mingw32]
