Rails 控制台无法在 ubuntu 12.04 上启动

Question

我正在使用 Rails 服务器，没有任何问题 ubuntu 12.04。但我想在终端上的控制台上尝试一些方法，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了 ruby​​ 1.9 引入的新哈希语法。看起来您正在使用 ruby​​ 1.8 运行该应用程序。

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地方。

哈希语法的区别在于：

1.9

{key: 'value'}

1.8

{:key => 'value'}
