ruby-on-rails - 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 Ruby 1.9 和 Rails 2.3.4 中启动控制台 (irb)。我安装了两个版本的 Ruby(1.9 和 1.8.6)，并且通过调用以下命令运行 Ruby 1.9:rake19、ruby19、gem19...etc

除了这个之外，它们在所有情况下都能正常工作!看起来它正在尝试加载 Ruby 1.8!你知道我该如何改变吗？

发生这种情况是因为脚本/控制台正在调用 irb (1.8)。假设你有 ruby​​ 1.9 的 irb19 你可以这样做:

script/console --irb='irb19'

但是，rails gem 仍然可能存在问题。如果是这样，我建议使用 rvm管理您不同的 ruby 。使用rvm时，您需要分别为ruby 1.9和1.8安装gems。
