getting this error

[laurensius]

I get the same issue. Has anyone managed to solve it?

[FoRavel]

I had the same exact same issue after I upgraded my react-native version to 0.74.0. I finally decided to revert back to my initial version which was 0.72.7 and it solved the issue.

I also reverted "@types/react": "18.2.79" to "^18.0.24", which was my initial version before upgrade.

I am getting this issue as well.
[!] Invalid Podfile` file: uninitialized constant Pod::Podfile::FlipperConfiguration.

from /Users/xxxxx/Documents/xxxxx/xxxxx_iOS/ios/Podfile:18

-------------------------------------------

# ```

flipper_config = ENV['NO_FLIPPER'] == "1" ? FlipperConfiguration.disabled : FlipperConfiguration.enabled

-------------------------------------------`

[gibo77]

Debugging React Native apps with Flipper is deprecated in React Native 0.73.

[gibo77]

In my use case, I don't use Flipper. So I removed them in Podsfile.
Line 18

...(process.env.NO_FLIPPER ? { 'react-native-flipper': { platforms: { ios: null } } } : {}),

```

#flipper_config = ENV['NO_FLIPPER'] == "1" ? FlipperConfiguration.disabled : FlipperConfiguration.enabled

Line 43

you should disable the next line.

#:flipper_configuration => flipper_config,

An absolute path to your application root.

Basically put # before the Flipper line on the two lines.

Then run "pod install" inside "iOS" folder.

It will run for a while. For me it took few minutes.
Pod install took 286 [s] to run

Mine run below, just a snippet and not all

Debugging React Native apps with Flipper is deprecated in React Native 0.73.

How do I enforce that in an Expo app?

[gibo77]

I am not in Expo.
Can you put # on the Flipper at Podfile? This are only two lines as stated above.
Then run "pod install" in iOS folder.
After that it will automatically delete the Flipper since this is not used anymore by React Native after 0.73.

Podfiles are abstracted away in Expo, so no, unfortunately.

[ChrisWiles]

Same issue, using RN 0.74.0

Invalid Podfile file: uninitialized constant Pod::Podfile::FlipperConfiguration.

[brentvatne]

@orome

they aren't actually, you can run npx expo prebuild -p ios to generate the Podfile. (this is called continuous native generation).

can someone share a minimal reproducible example?

[ChrisWiles]

I would love to upgrade to React Native 0.74. According to the React documentation, Flipper can still be used, but this bug is currently preventing the upgrade.

[brentvatne]

@ChrisWiles - can you share a minimal reproducible example?
