Cocoapods 错误，而运行 ios 应用导致 pod 安装错误

Question

我正在尝试同时创建 ios 和 android 应用程序，它适用于 android 但适用于 ios 而运行 flutter run 使用pod install安装pod会花很多时间，最后会报错如下图

Error output from CocoaPods:
↳
         Cloning into
         '/var/folders/f6/g4njsx3x5tx5dswcbsh29tdh0000gn/T/d20210605-16785-1rc0t
         ko'...
         fatal: unable to access 'https://github.com/grpc/grpc.git/': Failed to
         connect to github.com port 443: Connection refused
Error running pod install
Error launching application on iPhone 12 Pro Max.

我尝试了这些帖子，但没有成功
error running pod install
error running pod install pods-runner

pubsec.yaml

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^1.0.2
  image_picker: ^0.6.7+17

  image_cropper: ^1.4.0

Answer 1

经过多次研究，我找到了解决方案，

第 1 步：我使用

删除了所有 cocoapods 及其目录

gem list --local | grep cocoapods
sudo gem uninstall EACH_OF_THEM  // here EACH_OF_THEM means all the listed cocoapods
rm -rf ~/.cocoapods

第 2 步：安装 HomeBrew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

第 3 步：使用 HomeBrew 安装 cocoapods

brew install cocoapods

第 4 步：删除 Podfile.lock（如果存在）

cd ios
rm Podfile.lock

第 5 步：现在安装 pod

pod install --repo-update

It will take lot of time to download and install all the dependencies.

现在，如果我运行 flutter 项目使用 flutter run。成功了

...
Running pod install...
Running Xcode build...
