感谢您的推荐 关于我以前的操作系统从Windows 7更改为ubuntu 12.04的问题，我有一天感到震惊。 在我的Windows中，symfony应用程序运行在PHP 5.5.6上，在5.5.6版本中运行的ubuntu应用程序中运行相同。但现在我得到了实体关系中的错误。我试图解决它，但我没有成功。
相同的代码也在另一个Windows 7系统上运行，但我需要在linux中运行。
请为我提供解决方案。
以下链接是dropbox，您可以在其中找到所有实体。
访问https://www.dropbox.com/sh/rr7d31ah71sagwp/AACb7LW3r0R8ugvaDmkvERACa?dl=0
以下是错误：
检测到异常！ 目标实体Collegelife \ CommonBundle \ Entity \ countrycity在＆＃39; Collegelife \ CommonBundle \ Entity \ Country＃countrycityassociation＆＃39;中找不到。
