Make sure that:

• ruby for Windows is installed
• your %PATH% is modified to reference ruby (Advanced System Settings / Environment Variables / System Variables / Path: enter: C:\Path\to\Ruby\bin;)
• rubygem is installed. (If you use rubyinstaller, that should be already the case)

Then open a new CMD session, and type bash (the bash from Git should open).
Then ruby should be available, including gem.
