Same problem here with macOS 10.12.6, React Native 0.47.1, Node 8.4.0, react-native-cli: 2.0.1

[kitsoftwaregroup]

Any fix with this issue ?

[huzcNo1]

Maybe because of "babel-preset-react-native": "3.0.0" ， I have solved this problem by back to 2.1.0

uninstalling watchman fixed my issue

[duanj3]

@FaridSafi dude, I don't think I have installed watchman, couldn't find it at all

[afeifly]

"babel-preset-react-native": "3.0.0" change to 2.1.0 . still same problem.

[duanj3]

@huzcNo1 I think I have downgraded the version of react-native, the current version of react-native-cli is 2.0.1, but still doesn't work, and how do you back it to 2.1.0?

[huzcNo1]

@duanj3
yarn remove babel-preset-react-native
yarn add [email protected]

[duanj3]

@huzcNo1 yeah, that's exactly what I did before, and react-native-cli just automatically turned to 2.0.1, I mentioned in the issue as well, thanks anyway, have you got Wechat (QQ) or something if it doesn't bother you, cause I want to check that I didn't make it wrong

[huzcNo1]

Can I have a look the file of package.json in your project @duanj3

[duanj3]

@huzcNo1

oh, it shows "babel-preset-react-native": "3.0.0", what can I do?

[huzcNo1]

do this in the root dir of you project
yarn remove babel-preset-react-native
yarn add [email protected]
