win7 rails aptana studio 3 + rmagick + bundler cannot start debug server

i've been trying to start 'debug server' for a rails application in aptana studio 3 but i never succeeded. every time i tried to start debug server, exception thrown: Uncaught exception: Could not load the bundler gem. Install it with gem install bundler.

1. i followed the aptana studio 3 getting started guide and installed everything except rvm (i don't know how to install it on windows). is it really necessary for aptana studion 3 on windows? i have only 1 ruby version installed.

2. i installed rmagick successfully and i put 'require rubygems' and 'require RMagick' in preinitializer.rb. am i putting them at the right place?

3. i use bundler for gem management and i can successfully start the server by running "ruby script/server". i just don't know what's wrong with the debug environment. am i missing some PATH setting?

4. any body running smooth with aptana studio 3, rmagick and bundler. can tell me your 开发者_开发百科settings?

thx.

Ah found the problem. The environment needs to have a ‘MAGICK_CODER_MODULE_PATH’ variable added that points to your ImageMagick modules/coders installation path. You can add this in the "Environment" tab of your debug configuration for the project.
