问题
I have installed RedCloth, by using the devkit. Using gem install RedCloth.
If I use plain irb, then require 'RedCloth' works fine.
But if I use rails console and do require 'RedCloth', it says it can't find file to load.
Please help.
Rails 3.0.0 RedCloth 4.2.3
回答1:
Is RedClotch included in your Gemfile, and have you run bundle install since updating your Gemfile?
I don't believe Rails 3 will allow you to include gems that are not in the Gemfile. I'm not quite sure about the inner workings of bundler, but I believe the Rails app considers your Gemfile it's "only source" for loading gems.

Make sure to do the following on Windows XP and above!
- Installed Ruby via rubyinstaller.org
- Downloaded DevKit from rubyinstaller.org
- From the Ruby enhanced CMD prompt, "ruby dk.rb init", followed by "ruby dk.rb install"
- Downloaded the SQLLite DLL files from here: sqlite.org, copied them into the C:\Windows directory
- From the Ruby enhanced CMD prompt, "Gem install RedCloth"
- Added "Gem RedCloth" to gemfile
- "bundle install"
These steps worked for me! I don't understand why people have such a hard time with Ruby on Windows. That's all I develop on and it works fine.
