几天来，我一直在为 Rails 应用程序苦苦挣扎。我尽我所能，问了一些关于 SO 的问题，并试图收集我能收集到的所有信息和技巧。这是摘要：

几天前，当我运行时rails s，我知道我删除了 ruby​​-2.0.0-p0，得到以下信息：

`require': dlopen(/Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle, 9): Library not loaded: /home/.rvm/rubies/ruby-2.0.0-p0/lib/libruby.2.0.0.dylib (LoadError)
      Referenced from: /Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle
      Reason: image not found - /Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle

有人告诉我这可能与 RVM 有关。我从 RVM 切换到 rbenv，并卸载/重新安装了 Ruby（不是内置的 OS X）和 Rails，运行时得到了相同的消息rails s。

然后我完全卸载并删除了 Macports 并再次尝试使用 rbenv 并得到相同的消息。

我试图符号链接/home/.rvm/rubies/ruby-2.0.0-p0/lib/libruby.2.0.0.dylib到/usr/local，我得到了同样的信息。

我试着玩出口DYLD_LIBRARY_PATH，但我得到了同样的信息。

我卸载了 rbenv、Rails，然后返回到 Macports 和 RVM，但仍然收到相同的消息。

有人可以帮忙吗？

我正在使用 OS X。

ruby -v outputs ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.4.0] rails -v outputs Rails 3.2.13

我删除了 ruby​​-2.0.0-p0。

您的 rails 认为它​​应该使用--deployment/ 或--path来自 bundler - 这是通往 gems: 的路径/Users/git/gitlab/vendor/bundle/ruby/2.0.0/gems，不幸的是，bundler 足够聪明并且无法正确处理 ruby​​ 中的更改，您需要再次删除整个rm -rf /Users/git/gitlab/vendor/bundle目录bundle install。

我建议您停止使用捆绑器中的--deployment/ 或--path标志，删除目录rm -rf /Users/git/gitlab/vendor/bundle，rm -rf /Users/git/gitlab/.bundle/并在 gemset 中安装 gem，这样这个问题就不会再发生了。

在 capistrano 部署的情况下，将此标志设置为bundler/capistrano：

set :bundle_dir, ''
set :bundle_flags, '--system --quiet'

防止在捆绑器中使用--deployment和--path标记。
