[Bug] iOS Resolver Failed to install CocoaPods for the current user but Cocoapods are installed on macOS Monterey M1 Max

[Kharion]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2021.3.15f1 Personal
• External Dependency Manager version: 1.2.174
• Source you installed EDM4U: .unitypackage (.unitypackage or Unity Package Manager)
• Features in External Dependency Manager in use: Android Resolver, iOS Resolver (Android Resolver, iOS Resolver, VersionHandler, etc.)
• Plugins SDK in use: Firebase, IronSource, Facebook (Firebase, Admob, Facebook, etc.)
• Platform you are using the Unity editor on: Mac (Mac, Windows, or Linux)

[REQUIRED] Please describe the issue here:

iOS Resolver Failed to install CocoaPods for the current user:
Do a fresh install of macOS Monterey or buy new M1 Max Macbook Pro. Install Xcode 14.2 Install Homebrew with Command Line Tools (14.2). Install Cocoapods via Homebrew for M1 architecture. Do fresh install of Unity 2021.3.15f1. Check the pod --version to confirm Cocoapods 1.11.3 are installed and working. Check the ruby version to confirm you have default ruby version installed.
Note: It also happens if Ruby is updated to most recent one 3.2 (with chruby ruby-3.2.0 and PATH updated)
Open Unity project that contains External Dependency Manager
Toggle off Auto Install Cocoapods due to iOS Resolver inability to auto install already installed Cocoapods
Run the build.
Build finishes but pod install is not executed despite the Cocoapods are installed.

Expected behaviour: Pod install is executed correctly if Cocoapods are installed and the built project contains generated xcworkspace.

Workaround: Toggle off "Use Shell to Execute Cocapod Tool" in the iOS Resolver Settings and run pod install manually from the Xcode project build folder.

Please answer the following, if applicable:

What's the issue repro rate? (eg 100%, 1/5 etc)

This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @Kharion,

I have previously encountered this issue before using that macOS version, and it appears to be caused by Cocoapods 1.11.x. This can be fixed by either including export LANG=en_US.UTF-8 in your shell's profile or downgrading Cocoapods to 1.10.2. However, I recommend that you update your macOS version so that it can have the latest fixes and updates.

That said, I'll be closing this for now. Let me know if an issue arises.

[Kharion]

Hi @paulinon thanks for the help. I can confirm that with installing Cocoapods 1.10.2 the problem is resolved and xcworkspace is generated. But I must say this is still a workaround and you should not close the issue, but resolve it until the External Dependency Manager works with latest Cocoapods out of the box.

M1 Macs on Monterey have been out for over a year, so I am sort of surprised that the only fix to this issue seems to be in github issues here. Thanks for posting the solution: After about 4 hours of installing uninstall ruby, cocoapods, chruby, unity, etc - who should have known it was simply to downgrade cocoapods!

[copyandexecute]

I have the same issue 👍

[rxra]

none of the solution seems to work with me.
I am not using the default ruby version installed but one installed using rbenv (2.7.6). But I think I will also try with the default 2.6.0 embedded with OSX.
Here is the error I have. Any idea ? I am trying differents (reinstall, different versions, ....) seems 2 days and I am completly stuck.

[joksa]

Grrr everything worked before I updated Ruby required by another project. Now, I am stuck with the same issue

[Kharion]

Unfortunately you can see that this issue was closed and no response from developer. Maybe to create a new issue? I don't know why and I know that I confirmed that fix worked, but suddenly I don't know why the iOS resolver started trying to install Cocoapods again with failing result. This issue should not be closed and the proposed solution stops working. Maybe because I have installed other Cocoapods versions but surprise surprise if you are iOS native developer you have to have more Cocoapods versions. I mean I don't want to sound like a jerk but this issue still remains and should not be closed.

Bonus bug: the iOS Resolver settings keep getting reset by I don't know what and even if I disable the Use Shell to Execute Cocoapod Tool and Auto Install Cocoapod Tools in Editor for several times this checks get reset and the dependency manager is trying to install the Cocoapods. It's becoming really annoying.

This has been a persistent issue with my project for the past, week or so.
Urgently needs fixing not solely a workaround.

Workaround inherently creates more errors due to out of date dependencies and such.
