I am trying to compile my React Native application with Expo and for some reason, I keep encountering this issue with react native reanimated. I have removed and installed this package several times, and nothing is working. I even tried removing that line in the appropriate file within the node_modules folder, but it appears that deleting the line had no effect, as this error continues to pop up. I tried changing versions of react-native-reanimated as well. Has anyone else experienced this issue? Is there a solution to this?

My app is working fine on the web but stuck on the XCode Simulator upon running the initiating cmd expo start
List of files
Tried removing node_modules , package-lock etc but nothing seems to work
App has been reloaded numerous times but only works on web.
I found where the problem was, having expo-splash-screen was causing this issue. I was using this in a useEffect to load my project font but having removed this package resolved the issue.
I am an intermediate react developer.
I was running my react native app peacefully without any problems untill one morning, i did not change anything in my codebase but when i tried to run the app through expo client, it started showing the error in the screenshot.
I have checked and checked this platform, and not a single solution.
I am currently using expo sdk 43 (managed workflow) please help...this is my first time posting here.
This is the error below;
Can't find variable: require
http://127.0.0.1:19000/node_modules/expo/AppEntry.bundle?platform=android&dev=true&hot=false&minify=false:5:24.globalcode#http://127.0.0.1:19000/node_modules /expo/AppEntry.bundle?platform=android&dev=true& hot=false&minify=false:720:3.
Click here for the screenshot of the error
I got it fixed.
See what i did,
I created a fresh expo project using "expo init"
Then copied all my files into the new project "except node_modules and .expo folders".
Then i ran "npm install"
Viola!!! Everything works fine now
Note: i tried removing "node_modules" before over and over again and it dint work.
The only thing that worked was starting a new project and following the above steps.
I have a react-native app. I recently moved to react-native version 0.61.5 for which I took the long route of creating a new react-native app and porting my code over to avoid any linking issues since new version used PODFILE as the default linking mechanism. Ever since I moved to version 0.61.5, I don't get the correct location of code in error logs. I think this is mainly happening when the code is running in asynchronous fashion which most of the code is. For e.g., look at below screenshot:
It is reporting that it is not able to call map on some array which is apparently undefined but the place where the error is reported is completely incorrect. I have no such file in my codebase and it is probably pointing to some file in some react-native package.
I am using Sentry #sentry/react-native": "^1.1.0". I don't think Sentry can cause issue with the sourcemaps reported during development.
I am not sure how to debug this problem. This problem is causing a lot of issues in debugging any errors as I have to manually figure out where the error happened. Please let me know if you have any tips on how to fix this problem.
After upgrading to React Native 0.42 in order to get FlatList support, My app no longer runs properly. I get the following error:
The only related information I could find was this github issue for react-navigation a package which I am not using.
Can anyone suggest a way to debug this issue, or any fix to get rid of it.
I have tried the usual deleting node_modules and re-installing.
UPDATE
I have isolated the issue to the Navigator component, As I stop receiving this error if I simply render the initial route without the Navigator
But a new app created with react-native init didn't have any trouble rendering a Navigator
very much at a loss as to how to procede. Thanks in advance.
It turns out I simply forgot to clear the build directory under ios, which resulted in running new Javascript on an old native build. Removing this showed me merge conflicts in the ios files.
For me was not enough to remove the ios/build folder what I worked was to execute react-native upgrade which re-creates the bundle of the dependencies at the mentioned folder
I upgraded to react-native 0.16.0-rc, ran npm install, then ran react-native upgrade. When trying to launch the iOS app in a simulator (or device, doesn't matter) I get the error:
[error][tid:com.facebook.React.RCTExceptionsManagerQueue] Unhandled JS Exception: babelHelpers.interopRequireDefault is not a function. (In 'babelHelpers.interopRequireDefault(_reactNative)', 'babelHelpers.interopRequireDefault' is undefined)
I've just about run out of ideas here. Is there something I need to add to my xcode project maybe? Merging the latest react-native templates into mine was a nightmare so maybe something got messed up there.
This problem is discussed in this Github issue and fixed by this commit. You can apply this patch temporarily until it is merged into the project with the version 0.16.
