Fix Cygwin Issue with RubyGem
//We must add the following to your .bashrc (C:\cygwin\home\user\.bashrc):
alias ruby='/cygdrive/c/Ruby21-x64/bin/ruby'
alias gem='/cygdrive/c/Ruby21-x64/bin/gem.bat'
alias irb='/cygdrive/c/Ruby21-x64/bin/irb.bat'
alias compass='/cygdrive/c/Ruby21-x64/bin/compass.bat'

To load all files in the C:/Ruby32-x64/bin in Cygwin at once, I loop through all of them like this:

export RUBY_BIN="/cygdrive/c/Ruby32-x64/bin"
for file in $RUBY_BIN/*.bat; do
  base=$(basename -- "$file")
  cmd="${base%.*}"
  alias $cmd="$file"
done

Anf finally, I put this inside ~/.bash_profile as bash doesn't automatically load ~/.bashrc
