When upgrading to 0.64-rc3, error: Cycle in dependencies between targets 'FBReactNativeSpec'

[esilverberg]

Description

When upgrading to 0.64-rc3, I was stuck for many hours today on this compliation error:

Cycle in dependencies between targets 'BVLinearGradient' and 'FBReactNativeSpec'.

The initial target is irrelevant; if I removed BVLinearGradient it would still happen for many different native libraries and FBReactNativeSpec.

React Native version:

0.64-rc3 on iOS

Steps To Reproduce

Repro was consistent in my project. Maybe has something to do with the fact that I use use_frameworks!, and in the latest sample Podfile React Native does not include this directive.

Workaround

I was able to workaround this issue (and thus want to document it here for others who may get stuck) by:

Navigating to the FBReactNativeSpec target in the Pods project and deleting [CP-User] Generate Specs step.

I then navigated in the terminal to:

<project>/node_modules/react-native/scripts

And I manually ran from the terminal:

./generate-specs.sh

Make sure to update all your dependencies that rely on React as a dependency in podspec to a version that relies on React-Core. (Just ran into this issue a few hours ago)

Do you need help upgrading to a newer React Native version? Visit the Upgrade Support repository or use the upgrade helper to see the changes that need to be made to upgrade your app.

[esilverberg]

I am pretty confident this is not an upgrade issue. Every single time I run pod install, I see [CP-User] Generate Specs re-added to FBReactNativeSpec and I must delete it each time to ensure the build does not fail with this message.

[schmidan]

I seem to be running into the same issue.
The workaround by @esilverberg does work but needs to be done after every pod install.

Showing All Messages
Cycle inside FBReactNativeSpec; building could produce unreliable results. This usually can be resolved by moving the shell script phase '[CP-User] Generate Specs' so that it runs before the build phase that depends on its outputs.

[!] FBReactNativeSpec has added 1 script phase. Please inspect before executing a build. See https://guides.cocoapods.org/syntax/podspec.html#script_phases for more information.

don't know if related, but I had similar problems and workaround works. but my issue was related to thing that I started ios build with yarn. it's related somehow to the fact that this Generate Specs is npm script and won't execute correctly if you run with yarn. after I tried just npx react-native run-ios from manual -> build success.

[billnbell]

This is not resolved. Still happens on 0.64.x

[marf]

Same problem here.

[paulxuca]

We've fixed this by moving the build phase that react native adds before the headers phase (It is added after by default)

[billnbell]

Is there a release ?

[JB-CHAUVIN]

Same problem goes for me, what is the solution ?

How did you do that ?

[paulxuca]

@JB-CHAUVIN

Click on the Pods project on the left sidebar
Go under Build Phases
Make sure [CP-User] Generate Specs is before Headers

[marf]

Is there a permanent patch for this? Because the fix works the problem is that we have to re-do it every time we run pod install
