Can't convert html.erb's to haml with the "erb2haml" gem on Windows

Question

Solved. Look at my answer below.

My Problem: I just can't convert all my html.erb's to haml. I tried the erb2haml gem with the "rake haml:replace_erbs" command but it doesn't work. Here is the full error:      

C:\xampp\htdocs\Ruby>rake haml:replace_erbs --trace

Tasks: TOP => haml:replace_erbs

It seems that the gem tries to use the "which" command on my Windows machine, what wouldn't make sense because it doesn't exist on Windows. Is there maybe a way to replace the linux/mac "which" command with the Windows "where" command ? If not, is there a other way to replace all html.erbs to haml's at once ?

I hope you can help me. Thanks.

I found a really easy and good way. First install the "haml-rails" gem if you haven't already, then just insert

rake haml:erb2haml

in the Console. It converts all .erb views into .haml . Works very fast and flawless.
