无法使用Ruby 1.9和Rails 2.3.4启动脚本/控制台

Question

我正在尝试在Ruby1.9和Rails 2.3.4中启动控制台(irb)。我安装了两个版本的Ruby1.9 (1.9和1.8.6)，我通过调用: rake19，ruby19，gem19...etc来运行Ruby1.9

它们在所有情况下都工作得很好，除了这个！看起来它正在尝试加载Ruby 1.8！你知道我能怎么改变这一点吗？

这是因为脚本/控制台正在调用irb (1.8)。假设你有Ruby1.9的irb19，你可以这样做：

script/console --irb='irb19'

然而，rails gem可能仍然存在问题。如果是这样，我建议您使用rvm来管理不同的rubys。当使用rvm时，您需要分别为ruby 1.9和1.8安装gem。
