- 安装的时候务必保持全程代理，ClashX中有一键复制命令行代理的命令
- 保持 metro版本和react-native版本要一致，否则会有函数解析不成功的问题 "metro-react-native-babel-preset": "^0.63.0",
For us this was caused by a version mismatch of the metro-config package. If you depend on this in your app to override some default metro configuration you should make sure it's the same version react-native depends on. In our case we upgraded to react-native@0.63.2 and also upgraded metro-config to 0.61, although react-native depended on 0.58. This caused the metro version used by the react-native CLI to try to load a transformer module from a path that does not exist for 0.58, returning undefined from the require call, leading to the error in question. You can check which versions are required and installed by running npm ls metro-config or searching the package-lock.json file.
