cannot install rails plugins

My problem is: ruby script/plugin is not working (I don't see any HTTP traffic, nor an error message or something) What can be failing? Did I forget to setup something?

My progress so far (using Windows XP):

• Unpacked hxxp://files.rubyforge.vm.bytemark.co.uk/rubyinstaller/ruby-1.9.1-p378-i386-mingw32.7z (to d:\prog\Ruby)

• Unpacked hxxp://files.rubyforge.mmmultiworks.com/rubyinstaller/devkit-3.4.5r3-20091110.7z (to d:\prog\Ruby\devkit)

• Unpacked hxxp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p378.tar.gz (to d:\prog\Ruby\sources)

• Fi开发者_StackOverflow社区xed ./devkit/msys/1.0.11/etc/fstab

• Set http_proxy=myproxy:8080

• Unpacked hxxp://files.rubyforge.vm.bytemark.co.uk/rubygems/rubygems-1.3.5.zip (to a temp dir)

• Executed rubygems-1.3.5\setup.rb

• Added these gem sources:

  http://gems.rubyinstaller.org

  http://gemcutter.org

  http://gems.rubyforge.org

• Did ruby gem install rails mysql mongrel. No problems here.

• Created my first rails app, ran without problems with the default scaffolding (Mongrel, not WEBrick).

• Then I tried to install some rails plugins, like ruby script/plugin install git://github.com/activescaffold/active_scaffold.git. Didn't find anything.

• So I tried ruby script/plugin discover, and it does nothing (no error, just returns)

I'll probably have to do something about that git thingie next, but the fact that plugin discover is doing nothing makes me suspect something else is broken here? The web proxy access is working OK for the gems, and I don't see any HTTP requests being made from plugin discover...

You can't install plugin by git if you have no git command. But git is not compatible in DOS console. You need use MsysGit

You can install plugin by download the plugin from github and extract all source in your /vendor/plugins directory. All directory in this path are load by plugin
