flutter - Cocoapods 找不到 pod Firebase 的兼容版本

Question

我刚刚从 Windows 10 切换到 Mac。我已经发布了我的 Flutter 应用的 Android 版本。现在我正在开发我的 Flutter 应用程序的 IOS 版本。当我尝试在 Mac 上运行我的应用程序时，出现以下错误。

[!] CocoaPods could not find compatible versions for pod "Firebase/Core":

Answer 1

我通过运行手动 'pod update' 和 Flutter 'Packages get' 解决了这个问题...

在终端更改目录到:

cd FLUTTER_PROJECT_FOLDER_PATH/ios

运行 pod 更新:

pod update

运行 Flutter 包获取

flutter pub get 

• 那么你应该可以构建到iOS了

• 第一次构建确实比正常时间长了大约 3 分钟，但在接下来的构建中恢复正常。
