Creating batch file for installing rails gems

Hey,

I work on windows, and i want to make a batch file for installing all my
gems

i have creating install_rails_gems.bat

install_rails_gems.bat:

gem install pdf-writer --include-dependencies
gem install tzinfo --include-dependencies
gem install money --include-dependencies
gem install sentry --include-dependencies

But it only installs the first one :s:s

Can anyone help me?
