我将 RVM 与 Ruby 1.9.3 p448 一起使用，但是当我尝试运行我的 rails 服务器时，我得到了这个错误（加上其他一些东西） 

9): Library not loaded: /Users/sashafklein/.rvm/rubies/ruby-1.9.3-p327/lib/libruby.1.9.1.dylib (LoadError)
      Referenced from: /Users/sashafklein/rails/<appname>/vendor/bundle/ruby/1.9.1/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle
      Reason: image not found - /Users/sashafklein/rails/<appname>/vendor/bundle/ruby/1.9.1/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle

奇怪的是，它引用了 ruby​​-1.9.3-p327，它甚至不是我安装的 RVM 之一。我应该删除它没有找到 libruby 的那个 Ruby 文件夹吗？或者还有什么可能是错的？

编辑——完全错误

白化宝石似乎在这个底部，但我认为它是应用程序所必需的，所以我不能把它拿出来。我尝试了 gem uninstall albino （没有输出）然后捆绑安装，但这并没有解决任何问题。捆绑更新也是如此，下面是 mpapis 和 sahil 的帮助。

当宝石链接错误时可能会发生这种事情，试试这个：

rvm get head
rvm reinstall 1.9.3-p448
rvm use 1.9.3-p448

这将重新安装 ruby​​ 并使所有 gem 保持原始状态，这应该可以防止此类问题发生 - 除非 gem 作者做了一些超出标准 ruby​​ 检测的额外技巧。

更新

使用bundlers 标志--deployment或--path并不总是安全的，错误消息说：

/Users/sashafklein/rails/<appname>/vendor/bundle/ruby/1.9.1/gems/posix-spawn-0.3.6/lib/posix_spawn_ext.bundle

这意味着 gem 是用其他 ruby​​ 编译的，现在找不到它。

修复它的最简单方法是停止使用--deployment 标志，因为它是持久化的，摆脱它（以及所有其他潜在危险设置）的最简单方法是：

rm -rf .bundle/ vendor/bundle 
bundle install

解释

Bundler 在运行时过滤 gem 方面做得很好，不幸的是，它使用标志强制执行另一层过滤--deployment，这会强制将 gem 安装到多个 rubies 常见的路径 - 在这种情况下：ruby/1.9.1，这是不安全的，因为 rubies 可以使用不同的设置进行编译这可以破坏不同红宝石中使用的 c 扩展宝石。
