flutter - Flutter 构建失败并出现致命错误：找不到“Flutter/Flutter.h”文件

问题描述

我正在用颤振开发应用程序，

我收到致命错误：'Flutter/Flutter.h' file not found ，当我构建我的应用程序时出现此错误。

我尝试重新安装 cocoapod 并删除 podfile.lock 并重新安装它，

但我仍然收到此错误..

我该怎么办这个错误？

解决方案

转到终端，备份您的 ios/Runner 文件夹并删除您的 ios 文件夹。然后去终端执行

cd path/to/your/project/projectName
flutter create .
flutter run

如果颤动运行失败

cd ios
pod install
cd ..
flutter run
