android - 添加依赖项时，“Flutter build ios”失败

问题描述

从无到有，我...

  1. 在 Android Studio 中创建新的颤振应用
  2. 在 pubspec.yaml 中添加 font_awesome_flutter 依赖项

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  font_awesome_flutter: ^8.12.0
  provider: ^5.0.0
  flutter:
    sdk: flutter
  1. 在安卓模拟器上运行应用程序，运行良好但
  2. 在 iOS 模拟器上运行应用程序，得到这个错误：

Error running pod install
Error launching application on iPhone 12 Pro.

尝试运行flutter doctor，flutter clean，删除pods文件，在XCode中设置开发团队。纳达。

我也尝试过在多个项目中使用多个依赖项，结果相同。出于某种原因，我的开发环境根本不允许我运行 XCode 项目。一旦我添加依赖项并运行flutter build ios，或者尝试在ios模拟器上运行，问题总是会出现。我不确定在哪里看或如何开始纠正这个问题。我是 Flutter 和移动开发的新手。我正在运行 iOS Catalina 10.15.7。

解决方案

我在将flutter 1.17.5升级到flutter 1.22后遇到了这个问题，你最近升级了你的flutter SDK吗？对我来说，这很有效。

我ios/Flutter从我的目录中删除了该文件夹并运行了这些命令并将我的部署目标更改为 11.0

-> flutter create .
-> flutter pub cache repair
-> cd ios 
-> pod init 
-> pod install

遵循这些命令后，我可以在模拟器上构建 iOS 并创建存档。

为了更安全，请备份已删除的文件夹
