由于earlgray 2的pod版本目前已经相当过时，我尝试使用直接复制方法，并且有点拘泥于构建AppFramework。所以我遵循了这里的设置指南：Github 上的Earlgrey 2
git clone -b earlgrey2 https://github.com/google/EarlGrey.git
cd EarlGrey
sh Scripts/download_deps.sh
然后我在XCode中打开EarlGrey.xcodeproj文件，开始构建所有目标，除了ApppFramework之外，所有目标都构建得没有任何问题。但当我尝试构建AppFramework目标时，首先我在GreyAppStateTracker.m中遇到了一个关于使用self的错误(第361行(，我通过将_printAppStateTrackerLog更改为self->_printAppStateTrackerLog来修复了这个错误。但在第二次构建尝试中，我遇到了以下错误(如果我为arm或x86_64构建，那没关系，下面是我为arm64构建时的错误(，我无法修复：

我不太清楚为什么它看不到这些符号。。。如有任何帮助，我们将不胜感激。我使用XCode 12.0只是以防万一。
我遇到了同样的问题。看看的两个文件
CommonLib/Config/GREYAppState.mu2028
CommonLib/GREYLogger.m
它们当前不是项目的一部分，但应该是。添加它们，并确保两者的目标成员资格都设置为AppFramework。之后，AppFramework在我的系统上正确构建。
