[!] CocoaPods could not find compatible versions for pod 报错解法

[!] CocoaPods could not find compatible versions for pod "Camera":
In snapshot (Podfile.lock):
Camera (= 1.1.3)

In Podfile:
Service (from ../) was resolved to 4.6.15, which depends on
Camera (= 1.1.4)

You have either:

• changed the constraints of dependency Camera inside your development pod Service.
  You should run pod update Camera to apply changes you've made.

当报这样的错误的时候，执行更新本地库就好了 pod update Camera
