You can use the below patch with patch-package to ensure there's no duplicate declaration between @types/node and @types/react-native. I've not looked into both of these types so not sure where the intent to add them came from but at least it will give you a work around in the mean time.

@varwasabi thanks

Likely related to: https://github.com/react-native-community/react-native-template-typescript/pull/182

This is still happening when initializing with typescript template. Had to use @varwasabi patch.

[achmadk]

Is it possible to set compilerOptions.skipLibCheck inside tsconfig.json file to true instead, because these transpile errors occurred by third-party libraries?

[CptFabulouso]

As workaround I solved it by installing @types/node@14.14.2. Nothing seems to complain

Since this issue was open for a while already, we are closing this now with #245. While not the best solution, it solves that initial "broken state".
