Error running pod install

Whats odd is I was running builds for a few weeks no problem. I had to update some plugins inside the pubspec.yaml file then it all broke when building ios

I immediately googled my answered and found this stack overflow question here: Flutter Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified

They mentioned to:

You should uncomment your profile ios target.

I had already had that un-commented and set to platform :ios, '11.0'

I then did some more research and it looks like it could be a Mac M1 Chip issue: How to run CocoaPods on Apple Silicon (M1)

I followed the 2022 instructions there:

# Uninstall the local cocoapods gem
sudo gem uninstall cocoapods

# Reinstall cocoapods via Homebrew
brew install cocoapods

This failed and I think brought me into a bigger hole so I ran flutter doctor

        CocoaPods is used to retrieve the iOS and macOS platform side's plugin code that responds to your plugin usage on the Dart

        Without CocoaPods, plugins will not work on iOS or macOS.

I then clicked on the link and followed the instructions to update cocoa pods.

sudo gem install cocoapods

But if I run flutter doctor again, it still says its out of date…

Think I am in a worse place now.

Solution

To summarize a few keypoints here:

  1. Your cocoapods installation was broken. So try removing the brew version first via "brew uninstall cocoapods" Then install cocoapods via sudo gem install cocoapods.

  2. Your Podfile is referencing two different versions of the same package.

  [!] CocoaPods could not find compatible versions for pod "Firebase/Firestore":
      In snapshot (Podfile.lock):
        Firebase/Firestore (= 9.3.0)
 
      In Podfile:
        cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`) was resolved to 4.0.5, which depends on
          Firebase/Firestore (= 10.1.0)

This might also cause the build error. You could try to find versions of the plugins snapshot and cloud_firestore that don’t conflict with one another.
