然后跑

bundle update rack

我犯了以下错误

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    rails (= 3.2.8) ruby depends on
      rack (~> 1.4.0) ruby

    rack (1.5.1)

我跑

bundler: exec needs a command to run

尝试使用卸载机架

gem uninstall rack

跑

bundle install

可以使用此命令执行以下操作：

bundle update

这里有哪个版本的机架：/usr/local/rvm/gems/ruby-1.9.3-p125@global/gems/（如果您创建了应用程序的gems文件，则在应用程序的gems文件中，您应该这样做）？机架1.5.1可能已安装，但您的Gemfile需要1.4.4。。。您是否尝试过将GEM文件中的语句从1.4.4更改为1.5.1？@Sparda在主屏幕上进行更新，并尝试使用

bundle exec

？@icn确定，因此您的Rails版本依赖于rack 1.4.4，所以将1.5.1替换为

~>1.4.0

，像以前一样尝试更新您的GEM。如果不起作用，请尝试使用

gem uninstall rack

卸载rack，然后再次运行bundle安装。@Sparda非常感谢：）“gem uninstall rack”已解决问题如果您只在一个环境中工作，并且只需要安装一个版本的rack，这一切都很好，但是

bundle exec

（如错误消息所示）在这种情况下，有什么具体的解决办法。人们应该真正使用

bundle exec

，或者如果这是不可取的/不充分的，可以使用其他类型的gem集管理（例如rvm gemests）来确保项目在运行的任何地方加载相同的gems（例如dev vs prod）。通过gemests管理gems是我在对icn问题的第一次评论中建议的；）

bundle install

bundle update
