建议尝试以下，即工作对我来说：

Suggest trying the following, that worked for me:

a）从目标设置视图中的库中搜索，然后双击以检查库搜索路径的值

a) Search from 'Library' from the Target Settings view and double-click to inspect the value of Library Search Paths

b）列出了两个值 $（继承）和 $（PROJECT_DIR）/荚/建造/调试-的iPhoneOS 。删除后者。

b) There are two values listed $(inherited) and $(PROJECT_DIR)/Pods/build/Debug-iphoneos. Delete the latter.

c）做一个完整的清洁，构建和放大运行

c) Do a full clean, build & run

d）再次运行 pod install 。请注意，该条目未恢复。

d) Run pod install again. Notice that the entry is not restored.
