@changtimwu solved,I added "types": ["react", "react-native", "jest"] to my tsconfig but I still dont understand,what it does,maybe you can explain it ("types": ["react", "react-native", "jest"])

Adding "types" to tsconfig.json didn't work for me

Edit: because I didn't know you're supposed to add them under "compilerOptions"...

{
  "compilerOptions": {
    "types": ["react", "react-native", "jest"],
    // ...
  }
}

@savovs, Nice catch, that helped me a lot.

Unfortunately, when the compiler skips node, I still get errors, my project has dependencies on both node and react-native. Has there been any progress on this? Or are node and react-native mutually exclusive?

I am having same issue: as @stewhi added stackoverflow question.

When I remove the node types it gives me a lot of errors...

} 

For me, all I needed was:

{
  "compilerOptions": {
    "types": ["react"],
    // ...
  }
} 

... but this was a life saver!
