我在尝试运行任何单元或 UI 测试时遇到以下错误。运行应用程序本身时不会发生。错误信息如下所示：

我在 Swift 3.2 模式和 CocoaPods 中使用 Xcode 9。我正在使用 Firebase 和 FirebaseUI，它们具有 leveldb 作为依赖项。可以看到错误首先在leveldb/slice.h中触发，找不到string文件。

到目前为止，我已经尝试了以下方法：

清理（Shift + CMD + K）
删除 DerivedData
清理构建文件夹...
在构建设置的框架模块中允许非模块化包含。
pod deintegrate, pod clean pod install.

对于它的价值，这是问题导航器中的错误：

有什么建议吗？

【问题讨论】：

您解决了这个问题吗？我也有同样的问题。
您是否看到我在答案下发表的关于它工作的评论，应该将Enable Bitcode 设置为NO？我那不适合你，那我就帮不上忙了，很遗憾。

【解决方案1】：

这看起来类似于 CocoaPods 1.4.0 中修复的 CocoaPods issue。没有为单元测试目标正确设置搜索路径。

尝试更新到 CocoaPods 1.4.0 beta 并重新运行pod update

或者对 leveldb 路径使用与here 描述的类似的解决方法：

仅在 Build Settings -> Header Search Paths 下将 "${PODS_ROOT}/leveldb-library/include" 添加到您的测试目标

【讨论】：

我运行了pod update，然后 Could not build Objective-C module 'CoreGraphics 错误消失了，但现在出现以下错误：体系结构 x86_64 的未定义符号：ld：未找到体系结构 x86_64 的符号 clang：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）注意：未找到体系结构 x86_64 的符号 i>.
谢谢，它现在按预期工作！对于遇到我在上一条评论中提到的错误的任何人，请将 Enable Bitcode 设置为 NO。
我尝试了建议的解决方法，但没有解决任何问题。我还尝试更新到 CocoaPods 1.4.0 beta 2，而我得到的是 lipo: -remove's specified would result in an empty fat file。任何帮助，将不胜感激。环境：Xcode 9.1 使用 Swift 3.2。
