尝试通过可可豆荚构建可可伐木工/雨燕。编译最新的标签 3.2.0 最终会在 DDOSLogger.m 中出现错误下面是一个示例：

我已经更新了可可豆荚，用最后一个Xcode 8.3.1尝试了这个，清理了所有东西，等等......没有运气。令我惊讶的是，我找不到任何关于此的讨论......显然我没有收到消息，因为其他人要么可以工作，要么正在使用较旧的标签。
使用标签 3.1.0 工作正常，我相信它没有包含 DDOSLogger。
我不确定您是否设法解决此问题，但此处描述了类似的问题 - https://github.com/CocoaLumberjack/CocoaLumberjack/issues/883
从本质上讲，这是CocoaLumberjack中的一个错误，该错误出现在新版本的Xcode中，并且已经得到修复。
