每当我从终端运行此命令时:flutter build ios 在我的 Flutter 应用程序的项目根目录中,我都会返回:
Cannot find "xcodebuild". Xcode 9.0 or greater is required to develop for iOS.
为设备构建时遇到错误。 我有最新的 Xcode(10.0 版)。

我假设在我从外部 HD 运行 Xcode 时引发了 IOS 问题
最佳答案
我的问题的根源是 Flutter 找不到最新安装的 Xcode 版本。
要修复它,请转到 Xcode->preferences->locations->set value for command Line tools。
