I tried to install gem bootstrap-sass, but command show I have problem with ffi. I don't know what my problem? Thank you for your help me.
I received this error message when I tried to run gem install bootstrap-sass:
$ gem install bootstrap-sass
ERROR: Error installing bootstrap-sass:
The last version of ffi (~> 1.9.6) to support your Ruby & RubyGems was 1.9.25. Try installing it with `gem install ffi -v 1.9.25` and then running the current command again
ffi requires Ruby version >= 2.0, < 2.6. The current ruby version is 2.6.0.0.
Seemingly they were properly installed. ruby -v results in:
ruby 2.6.0p0 (2018-12-25 revision 66547) [x64-mingw32]
Seemingly they were properly installed. rails -v results in:
