Rails控制台无法在ubuntu 12.04上启动

Question

我使用rails服务器没有任何问题ubuntu 12.04。 但我想在终端上的控制台尝试一些方法，我使用

rails console

命令。 但它不起作用。 输出在这里：

那么，你有什么想法吗？ 我该怎么办？

Answer 1

看起来有问题的文件使用ruby 1.9引入的新哈希语法。 看起来你正在使用ruby 1.8运行应用程序。

1.）您可以安装和使用ruby 1.9 2.）您可以更改文件的哈希语法。 Rails 3.2.9应该与ruby 1.8.7一起运行，所以希望这是唯一有问题的领域。

哈希语法的不同之处在于：

1.9

{key: 'value'}

1.8

{:key => 'value'}
