【问题描述】：

我正在处理一个应用程序。在此之前我使用的是另一个版本的 XCode， （我不记得是哪一个了）但最后 ios 模拟器不起作用，我不得不更改为 xCode 12.5.1 的新版本。我的代码使用的是 Flutter 1.22。但是当我尝试启动我的 Xcode 构建时，我遇到了这种类型的错误。

无法为模拟器构建应用程序。 在 iPhone 12 Pro Max 上启动应用程序时出错。 退出（sigterm）

【参考方案1】：

错误来自您正在使用的插件之一，“flutter_device_locale”插件

我推荐使用device_info_plus，这也是flutter的最爱， 这是一个链接https://pub.dev/packages/device_info_plus

【讨论】：

谢谢，但我在 pubspec.yaml 文件中没有看到任何名为“flutter_device_locale”的包。如何更改此插件？在哪里？谢谢

这很奇怪，根据您发布的内容，它应该在那里，也许其中一个包取决于它？尝试运行“flutter clean”和“flutter pub cache repair”并重建
