这里和 Github 上已经提出了许多类似的问题，但没有一个解决方案对我有用。我一直在为这个错误挠头，如果你有任何线索，请帮忙。

在运行我的应用程序时，使用 firebase 身份验证，这就是我得到的

    [!] CocoaPods could not find compatible versions for pod "cloud_firestore":
      In Podfile:
        cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`)
    Specs satisfying the `cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`)` dependency were found, but they required a higher minimum deployment target.

我尝试删除 Podfile，取消注释 Podfile 中的“版本：'9.0'”，flutter clean，一切正常，但没有任何效果。我到底做错了什么？

标签： flutter dart cocoapods podspec

【解决方案1】：

如the ios documentation of FlutterFire（应该更突出）中提到的，FlutterFire supports an iOS deployment target of 10 or higher, in line with the requirements of the underlying firebase-ios-sdk.

解决办法，按照here的指示，设置部署目标为10。

不要忘记在更改后运行flutter clean。
