I installed:
ruby 2.3.3p222 (2016-11-21 revision 56859) [x64-mingw32]
When I run this command:
gem install sass
I face this error:
ERROR: Loading command: install (ArgumentError)
unknown encoding name - CP720 ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
and SASS doesn't work.
