Question

我正在尝试安装Flowplayer帮助程序gem，以便在Rails 3.1应用程序中使用，并通过RVM在OSX Lion上安装Ruby 1.9.3。

gem install flowplayer

正常完成，

也是如此

echo "gem 'flowplayer'" >> Gemfile

bundle install

当我尝试运行rails g flowplayer

时

我明白了：

我通过monkeypatching ~/.rvm/gems/ruby-1.9.2-p290@flowplayer/gems/flowplayer-0.1.2/lib/flowplayer/railties/generator/install_generator.rb文件躲过了这个问题。

我已将其改为：

module Flowplayer
  module Generator
    class InstallGenerator < Rails::Generators::Base
      (...)
    end
  end
end

为：

module Flowplayer::Generator
    class InstallGenerator < Rails::Generators::Base
      (...)
    end
end

不知道为什么，但它确实有效。

Rails 3.1 Flowplayer Gem安装
