Description

Bumped an existing 0.56.1 project to 0.57 and encountered an error on simulator start: _this._registerEvents is not a function on a clean project. Tried a new project from scratch and got the same error. Running Xcode 10 Beta.

Same error was mentioned in the following ticket: #20712

_this._registerEvents is not a function. (In '_this._registerEvents()', '_this._registerEvents' is undefined)

Reproducible Demo

xcode-select -s /Applications/Xcode-beta.app/Contents/Developer
react-native init AwesomeProject
cd AwesomeProject
node_modules/.bin/react-native run-ios

EDIT: Tried another new project and it worked this time. I guess it must be related to caching issues.

Will reopen if I can reliably reproduce.

eggybot · 2018-09-14T15:13:33Z

got the same issue.

onmyway133 · 2018-09-17T14:31:14Z

I got this issue on a clean new project as well. Currently I need to fallback to 0.56.0 to continue

#20567 by kelset

add the metro-react-native-babel-preset package
change .babelrc to
{
"presets": ["module:metro-react-native-babel-preset"]
}
npm run start --reset-cache
or
react-native start -reset-cache

chc200 · 2018-11-03T15:44:32Z

react-native start --reset-cache worked for me on @hbicexp solution

abrarum · 2018-11-04T19:31:00Z

Same error..

jankeesvw · 2018-11-06T10:32:08Z

We updated to React Native 0.57.4 and @babel/core 7.1.2 and our problem went away.

svenjens · 2018-11-08T14:35:36Z

Updating to React Native 0.57.4 and @babel/core 7.1.2 did not solve it for me.

jeremyblalock · 2018-11-09T02:03:36Z

Clean install doing nothing but react-native init RNTestProject produces this same error for me still.

diego-lipinski-de-castro · 2018-11-23T16:09:43Z

still a problem

bwoodlt · 2018-11-25T15:46:35Z

having the same issue after changing to apollo client 2.0

waltChang1 · 2018-12-18T07:58:16Z

same error

ricardodrs · 2019-01-04T11:48:52Z

Any solution for this issue? Nothing work for me :/

aligenc · 2019-01-24T08:20:28Z

it has been 1,5 year that I am coding with react-native. what i learned in this long time.

dont touch your released code
never mind doing something new

'cause all I have is these fc.g bugs with no solution.

ShooterArk · 2019-02-18T16:22:20Z

Did anyone found a solution for this? I am facing the issue for a while now! Cant make new projects cause they show the same error.. :/

mzxyz · 2019-02-18T21:34:39Z

@ShooterArk my react-native version is "0.58.4". The following steps fix my issue:

Delete the app, and use the clean the builder folder on Xcode.
Close Metro Bundler and use the Xcode to rebuild the app,
If still not working, try to run react-native start -reset-cache or yarn start -reset-cache -> yarn start then reload the app on client side.

Hope this can fix your issue

ShooterArk · 2019-02-19T19:37:21Z

@huanday I need to execute it on Android emulator!! I have already tried multiple times: react-native start -- --reset-cache.

Shabnam-Veranloo · 2019-04-14T13:32:08Z

my react-native version is "0.59.4" and have same issue

ptmt · 2019-04-14T17:48:29Z

Try commenting out setupDevtools in setUpDeveloperTools. I still haven't found the underlying issue, but since all I want to upgrade my old project, I will postpone the investigation.

SourceCipher · 2019-05-12T18:17:45Z

Why is this closed when the referred post has no solution apart saying to piss off and create a new project? I spent entire weekend trying to upgrade some libraries and its been a nightmare.. What a waste of time..

Now finally my project builds up and starts, but upon starting I have this issue as well.. I probably going to give up and just use ancient configs.. At least it works rather than stay up to date and have a pile of errors

MrShakes · 2019-06-02T14:21:43Z

After following @hbicexp 's instructions I had to restart my system to get it working/truly clear the cache(was still getting errors otherwise)

parasbansal · 2019-06-24T09:04:38Z

I had the same problem. I did the following and now it works fine:

watchman watch-del-all
rm -rf node_modules/.cache
react-native start --reset-cache
To be absolutely sure:
a. Uninstall the app from emulator/device.
b. Restart the system

parasbansal · 2019-06-24T12:21:19Z

Never mind. The problem was fixed but after about 30 mins it's back and this time the above solution is not working.
I even tried gradlew clean and npm cache clean.

Update:
I removed everything from .babelrc and left an empty object and now the app works perfectly.
Even after ~1.8 years of development in react-native, I have no idea about what is going on. :\

Subway19 · 2019-07-15T13:36:19Z

Facing the same issue.

Requiring module "node_modules/react-native/Libraries/Core/InitializeCore.js", which threw an exception: TypeError: _this._registerEvents is not a function

Tried all the methods mentioned above. This is the output of my react-native info

};

I tried:
#21094 (comment)
#21094 (comment)
#21094 (comment)
None worked.

Solution:

I removed 'react-native' from my babel.config.js and added a parenthesis on the render of App.js instead of making it an object.

Changed it from:

const App = () => {
  <Provider store={store}>
    <Navigation />
  </Provider>;
};

to

const App = () => (
  <Provider store={store}>
    <Navigation />
  </Provider>
);
