【问题描述】：

这是一个奇怪的问题，当我通过 android studio 在模拟器上构建和运行应用程序时，出现以下错误：

正在调试模式下在 iPhone SE（第 2 代）上启动 lib/main.dart... 升级 AppFrameworkInfo.plist 正在运行 pod 安装... CocoaPods 的输出： ↳ CDN：trunk 相对路径：CocoaPods-version.yml 存在！返回本地，因为检查只在 repo update 中执行

Error running pod install
Error launching application on iPhone SE (2nd generation).

但是当我从 Xcode 构建时，它构建完美。

【问题讨论】：

按照说明操作即可。
打不通。
在你的mac上打开terminal，输入命令export LANG=en_US.UTF-8和hit/press enter然后重启模拟器。
我已经这样做了，帮不上忙
你更新了~/.profile并执行了这个命令：source ~/.profile？

标签： ios xcode flutter android-studio cocoapods

【解决方案1】：

我的问题得到了一个简短的解决方案。依次运行以下命令后：

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
flutter pub get
cd ios
pod install
arch -x86_64 pod install (On an M1 mac use => arch -x86_64 pod install)

如果遇到 UTF-8 错误，请在此处运行此命令

export LC_ALL=en_US.UTF-8

然后再次运行arch -x86_64 pod install (On an M1 mac use => arch -x86_64 pod install) 命令。

终于跑了 flutter run命令启动模拟器

【讨论】：

PS：如果你的iOS文件夹中有任何断开的链接，你可以删除该文件夹并运行“flutter create -I swift .”命令重新创建它，然后运行上面的命令。
'flutter pub upgrade --major-versions'命令将依赖更新到最新版本。
