React-native: __DEV__ is not defined

[sarovin]

i have a [email protected] project on OSX.
I have deleted the node_modules folder and after i have given the following commands:

npm i
react-native upgrade

but I get this error:

> .../node_modules/react-native/Libraries/react-native/react-native.js:15
> if (__DEV__) {
>     ^
> 
> ReferenceError: __DEV__ is not defined

How do I fix? I can't run my project now...

Removing .babelrc seems to fix the problem.

My .babelrc:

{
  "presets": ["react-native"]
}

I use same config, but not meet the problem

You have [email protected]?
Can you try to delete the directory node_modules?
And after give:
npm i && react-native upgrade

I had not entered 'babel-preset-react-native' in my package.json

@sarovin @xuchuandong 666 has different meanings in different cultures. It represents a thumbs up in China. Haha.
