无法构建 Objective-C 模块 'CoreGraphics'

Question

我在尝试运行我的任何单元或 UI 测试时遇到以下错误。运行应用程序本身不会发生。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，它具有 leveldb 作为依赖项。可以看到首先在leveldb/slice.h中触发错误，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）
删除派生数据
清理构建文件夹...
在构建设置中允许非模块化包含在框架模块中。
pod deintegrate, pod clean pod install.

就其价值而言，这是问题导航器中的错误：

有什么建议吗？

Answer 1

这看起来类似于在 CocoaPods 1.4.0 中修复的 CocoaPods issue。未正确设置单元测试目标的搜索路径。

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

或对 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
