无法使用 Ruby 1.9 和 Rails 2.3.4 启动脚本/控制台答案

【问题标题】：can't start script/console with Ruby 1.9 and Rails 2.3.4无法使用 Ruby 1.9 和 Rails 2.3.4 启动脚本/控制台

【问题描述】：

我正在尝试使用 Rails 2.3.4 在 Ruby 1.9 中启动控制台 (irb)。我安装了两个版本的 Ruby（1.9 和 1.8.6），我通过调用运行 Ruby 1.9：rake19、ruby19、gem19...等

除此之外，它们在所有情况下都能正常工作！似乎它试图加载 Ruby 1.8！你知道我该如何改变吗？

【解决方案1】：

这是因为脚本/控制台正在调用 irb (1.8)。假设您有 irb19 用于 ruby 1.9，您可以这样做：

script/console --irb='irb19'

但是，rails gem 可能仍然存在问题。如果是这样，我建议使用rvm 来管理您的不同红宝石。使用 rvm 时，您需要为 ruby 1.9 和 1.8 分别安装 gem。
