react-native: React Native BUILD FAILED on run-ios

On Feb 8th 2021 still have this shitty error and everywhere is closed

@saulo1212 try to replace use_flipper! with use_flipper!({ 'Flipper-Folly' => '2.3.0' }) in your Podfile, then remove Podfile.lock and run pod install

I struggled to build react native project in iOS with this issue. And I did build after following processes.

1. Clear the cache of pod with

rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
rm -rf ~/Library/Developer/Xcode/DerivedData/*
pod deintegrate
pod setup

1. And delete the project’s Pods directory. The location of it is project directory > ios > Pods.
2. Then in the project directory > ios location, install pod with pod install
3. And react-native run-ios in project directory.

After I faced the issue, I try to build the project in another Mac and work fine. And I found the every error is from folly and it is in Pods. Then I compared Pods directory between mine and another Mac environment. In my case, there are missing files. So I reference the comment written by kelset in ‘folly/folly-config.h’ file not found, said “This happens when your pod cache is corrupted.”. So I check the way of clearing cache of pod, and it works.

Having this error too

use_flipper!({ ‘Flipper-Folly’ => ‘2.3.0’ })

–> this version no longer works as of writing. It should be use_flipper!({ 'Flipper-Folly' => '2.5' }) already

use_flipper!({ ‘Flipper-Folly’ => ‘2.3.0’ }) and use_flipper!({ ‘Flipper-Folly’ => ‘2.5’ }) didn’t work for me. The only way I could get to build is to comment out use_flipper!() completely.

Still facing this issue!!

Same as me, seems to have re-appeared +2

hello, I managed to solve my problem, sometimes it can work with you too, my pod was in version 1.10, I just returned to version 1.9, working normal so far.

It’s incredible that you need to reach this point to make it work, thank you.
