TypeError: undefined is not an object (evaluating 'GLOBAL.Text...

hi

I can't run the 'HelloWorld' successfully. I don't know what's wrong.

I have just installed [email protected] [email protected] [email protected] [email protected]. And I have initialized a new prject with react-native init HelloWorld without any error. Then hit run in Xcode. It shows me this:

TypeError: undefined is not an object (evaluating 'GLOBAL.Text = {
get defaultProps(){
throw getInvalidGlobalUseError('Text');}}')

This file throw an exception:

node_modules/react-native/Libraries/JavaScriptAppEngine/polyfills/document.js.

'GLOBAL' is undefined? node_modules/react-native/package.json shows version is 0.17.0-rc. Is it the correct version? How to fix this？

here is the solution

I reinstall the 'preset-react', remove the "presets": ["es2015"] from ~/.babelrc. Then add "presets": ["react"] to this file.

I'm having the exact same issue, though I was always able to run projects fine in the past. I don't have a ~/.babelrc folder. Am I supposed to have created one? Is that something new?

@natdm

You can create a new file called .babelrc

[natdm]

that worked, thanks!

Put this in your .babelrc:

{
    "extends": "react-native/packager/react-packager/.babelrc"
}

And that's it - you copy react-native settings for your whole project (so no conflict).
