Doing this :

rm -rf .babelrc

solves the issue temporarily

Manual react-native start works for me too after building everything else, as a workaround.

But the usual and complete react-native run-ios workflow is busted and still need fixing, obviously. The other workarounds posted previously (with .babelrc and such) doesn’t work for me.

This is happening on an existing project I just upgraded to 0.46.

I got it working by deleting .babelrc as per @javierM84

Closing the terminated process and booting up the packager via react-native start seems to work

I have the exact same issue when running run-android, while run-ios is working fine.

The problem occurs on newly generated projects, my existing projects run fine.

I also have the same issue. This is a temporary fix because I changed previous react-native package.json.

delete node_modules
change package.json

...
 "dependencies": {
        "react": "16.0.0-alpha.12",
	"react-native": "0.45.1"
},
"devDependencies": {
	"babel-jest": "20.0.3",
	"babel-preset-react-native": "2.0.0",
	...
},
...

do npm install
react-native run-ios

No need for manual install or deletes. With yarn, all you need is yarn upgrade. https://github.com/facebook/react-native/issues/14530#issuecomment-313747461
