ios - 无法使用firestore在IOS上运行flutter项目

Question

我无法在 IOS 模拟器上运行 flutter 项目。我已将 Cloud Firestore for Firebase 与该项目集成。该项目在Android设备上完美运行，但无法在IOS模拟器上运行。

如果有人能帮我解决这个问题，我将不胜感激。

当我运行 pod install 命令时，出现以下错误，请检查。

Answer 1

原因可能有很多。请提供错误或错误消息的屏幕截图，以提供更多信息。

我最近添加了 cloud_firestore，花了几天时间才解决 ios 的依赖问题。

一些常见错误是:

1. 版本兼容性 Firestore 至少需要 XCode 版本 10.1。
2. 未安装 Pod 文件。要解决此问题从终端转到 yourproject/ios目录并运行以下命令

pod install

确保您执行了此操作 Step

如果您可以提供更多信息或您执行的步骤，我可以进一步指导您。
