【问题描述】：

在我的 Flutter 项目中运行 pod update 后，我的项目不会为 iOs 编译。这就是我已经尝试过的。

删除 Pod 文件夹。
删除 Pod 文件
运行 Pod init 以创建新的 Podfile

【解决方案1】：

我自己修好了！

这是我所做的：

1. Make a new Flutter Project.

2. Copy all your files from /lib to the new project.

3. Delete the flutter/.pub-cache/hosted in your flutter Dir

4. Copy the `pubspec.yaml` file into new project.

5. Run flutter packages get

6. Delete the Pod folder in your PROJECT_DIR/ios folder, the Podfile.lock and the .workscape file (or just run 'pod clean' if you have the right cocoa pods version) 

7. Go into the PROJECT_DIR/ios folder and run pod install

就是这样，你的 Flutter 应用应该可以再次运行了 :)

【讨论】：

【解决方案2】：

@Konrad 的解决方案运行良好，除了 pod clean 在最新更新中已更改为：

pod cache clean --all

【讨论】：

【解决方案3】：

你可以尝试运行一个

flutter clean

我进行了 pod update 以更新 google maps sdk 版本，但我的 ios 项目停止工作。运行 flutter clean 然后尝试运行该应用程序，它又开始工作了。

【讨论】：

【解决方案4】：

也许这也可以帮助某人pod install --repo-update 这将更新所有 pod，即在升级颤振之后。
