CocoaPods could not find compatible versions for pod “React-Core“

报错如下：
[!] CocoaPods could not find compatible versions for pod “React-Core”:
In Podfile:
RNDeviceInfo (from ../node_modules/react-native-device-info) was resolved to 8.7.1, which depends on
React-Core

Specs satisfying the React-Core dependency were found, but they required a higher minimum deployment target.

解决办法参考如下：
Go to ./node-module/react-native-fetch-blob/react-native-fetch-blob.podspec & change

s.dependency ‘React/Core’
to

s.dependency ‘React-Core’

意思就是：进入到对应第三方库，找到.podspec文件
修改里面React-Core的写法。我的事将这个改成React/Core
这个写法就可以了。
