本文解决了在Windows环境下使用Rails插件CommunityEngine时遇到的样式丢失问题。通过修改Engines插件中的代码，确保了公共资产文件能够正确复制，从而恢复了社区引擎的样式。

CommunityEngine 是Rails下一个相当不错的社会化网络插件。

在linux下测试使用时候，相当的顺利，但在Windows下使用时，且在启动的时候出现以下错误，虽然可以正常启动，却发现样式全没了。

折腾半天，后来，发现，其实这根本不是CE的问题，而是CE用到的另一个插件Engine的bug

解决办法是：

打开Vendor/plugins/engines/lib/engines.rb

把第148行 #FileUtils.mkdir_p(base_target_dir) 调整为 FileUtils.mkdir_p(destination)

再次启动CE，发现，样式全回来了，SO cool。
