我想实现 firebase，为此我必须更新 pod。但是，当我在控制台中键入 pod repo update 时，它什么也不做……它只显示我的“更新规范 repo 'trunk'”，然后显示我的提示。如果我在控制台中输入 pod install ，它会显示：

[!] 无效的 `Podfile` 文件：/Users/tlobry/Desktop/Flutter/Generated.xcconfig 必须存在。如果您手动运行 pod install，请确保首先执行 flutter pub get。 # 来自 /Users/tlobry/Desktop/Podfile:16 # ------------------------------------------- # 除非 File.exist?(generated_xcode_build_settings_path) > raise "#generated_xcode_build_settings_path 必须存在。如果您手动运行 pod install，请确保首先执行 flutter pub get" ＃结尾 # -------------------------------------------

这是我的 pubspec.yaml：

name: flash_chat
description: A new Flutter application.

version: 1.0.0+1

environment:
  sdk: ">=2.1.0<3.0.0"

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  animated_text_kit: ^4.1.1
  firebase_core: ^1.0.3
  firebase_auth: ^1.0.2
  cloud_firestore: ^1.0.4

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:
  uses-material-design: true

  assets:
  - images/

这是我的 Podfile：

# Uncomment this line to define a global platform for your project
platform :ios, '9.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', 
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,


def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#generated_xcode_build_settings_path must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #generated_xcode_build_settings_path. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

【参考方案1】：

这是我过去尝试解决 Pod 安装问题的方法：

从 ios 文件夹中删除 podfile.lock
