[英]Flow - errors coming from react-native/Libraries

After migrating to Flow 0.101.0, I'm getting these new errors which are coming from react-native/Libraries : 迁移到Flow 0.101.0之后,我收到了来自react-native/Libraries这些新错误:

What is the best way to fix these errors? 解决这些错误的最佳方法是什么?

You should use the same version of with declared in the teamplate config. 您应该使用在teamplate配置中声明的with的相同版本。

For example, we use react-native@0.59 , for this version recommended use flow 0.92.0 例如,我们使用react-native@0.59 ,对于此版本,建议使用流程0.92.0

This is a typical react-native headache! 这是典型的反应性头痛! Thanks to the core team for this) 感谢核心团队的支持)
