ruby-on-rails - 使用了错误的 ruby​​ 版本

Question

我正在尝试让 Rails 在运行 Lion 的 Mac 上运行。我正在使用 rvm，它显示我正在使用 ruby​​ 1.9.2p312 但是当我去启动服务器时，我收到一个错误，引用 ruby​​ 1.8 并且即使在此错误之前我运行了 bundle install 并没有安装 rails它成功安装了我需要的一切。

关于如何解决这个问题的任何想法？

好吧，看来 1.8 的错误已经消失了。这是新的错误和捆绑显示:

如果使用 RVM，请确保在您的 ~/.bash_profile 文件中，rvm 的路径位于其他路径之前。

例如，在任何 PATH 声明之前将其放入 ~/.bash_profile 中:

export PATH=:~/.rvm/bin/:~/.rvm/gems/gems/

然后你的导出声明的其余部分可能看起来像这样(这只是一个例子，你不需要把它放进去，我只是把它包括在内，这样你就可以看到文件的样子，但上面那行你绝对需要):

export PATH=:~/bin/:/usr/local/Cellar/mysql/bin:/usr/local/Cellar:/usr/local/sphinx:/usr/sbin:$PATH

最后，如果你像我一样放弃了 RVM 并使用了 rbenv 那么替换第一个 export PATH与此相符:

export PATH="$HOME/.rbenv/bin:$PATH"

这些更改应该使系统先查看您的 RVM 文件，然后再查看 /System/Library/Frameworks/Ruby.framework 中的内置文件。

祝你好运。
