库没有加载错误 - 错误的红宝石

Question

我正在使用RVM和Ruby 1.9.3 p448,但是当我尝试运行我的rails服务器时,我收到此错误(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,这甚至都不是我的RVM安装之一.我应该删除那个Ruby文件夹吗？它没有找到libruby？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,但我认为它对应用程序是必要的,所以我不能把它拿出来.我尝试了gem卸载albino(没有输出)然后捆绑安装,但是没有修复任何东西.同样的捆绑更新,以及下面的mpapis和sahil的帮助.

Answer 1

当宝石链接错误时会发生这种情况,试试这个:

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

这将重新安装红宝石并使所有宝石保持原始状态,这可以防止此类问题发生 - 除非宝石作者做了一些超出标准红宝石检测的额外技巧.

更新

使用bundlers标志--deployment或--path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

这意味着宝石是用其他红宝石编译的,现在找不到它.

修复它的最简单方法是停止使用--deployment flag,因为它是持久化的最简单的方法来摆脱它(以及所有其他潜在危险的设置)是:

rm -rf .bundle/ vendor/bundle 
bundle install

解释

Bundler在运行时很好地过滤了宝石,不幸的是它使用--deployment标志强制执行另一层过滤,强制将宝石安装到多个红宝石常见的路径 - 在这种情况下:ruby/1.9.1这是不安全的,因为红宝石可以使用不同的设置进行编译这可以打破不同红宝石中使用的c-extension宝石.
