Report-native start report: Error: UNKNOWN: unknown error, open ... \. babel.json

Question

I have an RN development environment in Windows 7. It has been working fine until yesterday, and it suddenly reports an error after starting the "native response". Error message:

  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);

I have google error, no luck. I delete .babel.json, stiil error appears. I am creating a new project again, all the same. I uninstall node.js and python and then install them again following the “Getting Started” on the RN main page, all the same. I install response-native-cli 2.0.1 and 1.3.0, still the same.

The RN project seems to work even with an error. But you never know when an error will harm my project.

Answer 5

; %temp%/metro-cache .

( ), , :

1. Packager , /

2. react-native init ( expo), :

npm start -- --reset-cache

(those who use expo-clishould run expo start -cinstead of the above)

But, nevertheless, deleting a file ~/.babel.json(in a Windows file %userProfile%/.babel.json), as suggested here, cannot harm, I mean, I checked, and the above command was not deleted and / or modify the file .babel.json.
