Ruby on rails 每个Rails命令都失败了

我最近遇到了一个问题，在绝望中决定在我的OS X 10.6上卸载并重新安装Ruby和Rails。我已经重新安装了Ruby和gem安装的rails。不过，现在，每次尝试运行rails命令（偶数-v）时，我都会遇到此错误或类似错误：

rails-v

关于如何解决这个问题有什么想法吗？

看来您需要安装

---

也许可以尝试

sudogem安装bcrypt-ruby

？

运行

bundle-install

，然后运行

bundle-exec-rails-v

看看这是否可以解决问题。

假设您是从应用程序目录运行它，那么运行

bundle-install

时会看到什么？是否有包含

bcrypt ruby

的输出行？
