Error with Haml-rails: the file or directory is not found

It happens to me that I get this error when applying this command with Rails 5

rails generate haml:application_layout convert

It does not convert anything to me and I get this on the console

  

Errno :: ENOENT: No such file or directory @ rb_sysopen - C: / Users / Beto / Documents / Repos \     Use --trace for backtrace.

Use Windows 10. What possible solutions will there be?

I get the same when putting

rails generate haml: application_layout convert --trace
