Question

我被分配了一个用Ruby1.8和Rails2.3编写的预测。我们目前无法升级。我已经成功安装了ruby和rails，并在ubuntu机器上为项目安装了所有需要的宝石。我在安装所有内容时收到了成功消息。

但是，当我运行命令./script/server时，我收到了输出：

我是Rails的新手，非常感谢您对此错误消息的任何帮助。谢谢

问题的关键在于：

sentry (MissingSourceFile)

我真的不熟悉那个特定的文件（而且Rail 2.3是几个主要版本......）但它向我表明你的宝石套装有些不完整。

gem update

这将是我的第一次尝试。验证Gemfile中所有引用的gem都存在于系统中。如果可能的话，我真的希望升级到至少Rail 3，最好是4。

编辑：

再次阅读，你为什么要执行./script/server？你应该执行：

rails s

Ruby1.8 Rails2.3 ./script/server产生错误
