我正试图在运行狮子的我的mac上运行rails。我正在使用rvm并且它显示我正在使用ruby 1.9.2p312但是当我去启动服务器时我得到一个引用ruby 1.8的错误并且没有安装rails，即使在此错误之前我运行了bundle install和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，似乎1.8错误消失了。这是新错误和捆绑显示：
bundle exec rails s

如果使用RVM，请确保在〜/ .bash_profile文件中rvm的路径位于其他路径之前。
例如，在任何PATH声明之前将它放入〜/ .bash_profile：
export PATH=:~/.rvm/bin/:~/.rvm/gems/gems/
然后你的其他导出声明可能看起来像这样（这只是一个例子，你不需要把它放进去，我只是包含它，所以你看看文件的样子，但是以上你绝对需要）：
export PATH=:~/bin/:/usr/local/Cellar/mysql/bin:/usr/local/Cellar:/usr/local/sphinx:/usr/sbin:$PATH
最后，如果像我一样，你放弃了RVM并使用rbenv，那么用第一个export PATH行代替：
export PATH="$HOME/.rbenv/bin:$PATH"
这些更改应该使系统在/System/Library/Frameworks/Ruby.framework

我看到这已经得到了解答，但我建议只输入
gem install bundler或gem update bundler
它解决了OP在没有修改Bash_profile的情况下遇到的问题。
答案 2 :(得分：0)
我认为在使用带有不同rails版本的bundle和rvm时需要运行bundle exec rails s。
