缺少 RedCloth gem，但 `rake gems:install` 什么也不做
我尝试启动 Rails 应用程序，但从 Passenger 收到此错误消息：
Ruby on Rails application could not be started
The application has exited during startup (i.e. during the evaluation of
config/environment.rb)
/home/chuck/chuck.com/vendor/rails/railties/lib/rails/gem_dependency.rb:119:
Warning: Gem::Dependency#version_requirements is deprecated and will be removed
on or after August 2010. Use #requirement
Missing these required gems:
RedCloth
You're running: ruby 1.8.7.72 at /usr/bin/ruby1.8 rubygems 1.3.6 at
/home/chuck/.gem/ruby/1.8, /usr/lib/ruby/gems/1.8
Run `rake gems:install`
to install the missing gems.
我在应用程序中安装了 Rakefile 并尝试运行 rake gems:install 但没有任何反应，也没有打印错误消息。
我该如何解决这个问题？
I tried starting my Rails application but got this error message from Passenger:

Run `rake gems:install`
to install the missing gems.
I installed a Rakefile in my app and tried running rake gems:install but nothing happens and no error message is printed.
How can I resolve this problem?

我写了一些关于如何解决此问题的更具描述性的解决方案。需要修改environments.rd文件，添加
:lib=> 'redcloth'

我在使用 Rails 时有时也会遇到错误。我可能想知道它与超级用户命令有关，例如：
因为对我来说 rake gems:install 也什么也不做，我必须手动安装 gem 作为 sudo （我在这里谈论的是 Linux 盒子） ）。
I'm also getting errors sometimes when I'm using Rails. I might wonder its something to do with super user command, like:
Because for me also
rake gems:installdoes nothing and I have to manually install the gem as sudo (I'm talking about Linux box here).如果是rails-2.3.x，在你的config/enfironment.rb中
If it's rails-2.3.x, in your config/enfironment.rb
我发现 gems:install 参差不齐，因为人们在环境中放入了一些东西。rb 文件。如果此应用未使用捆绑程序，您应该
gem install RedCloth，然后重试。I have found that gems:install is spotty because of the things that people put in their environments.rb files. If this app isn't using bundler, you should
gem install RedClothand then try again.
