在Beta 0.3.2上使用Firebase-auth插件的Flutter的Xcode构建错误：不兼容的块指针

标签： firebase firebase-authentication flutter flutter-dependencies

这涉及flutter的{​​{1}}插件。 我在两台mac计算机上运行相同的代码。 我刚刚对后者进行了全新安装，并在FirebaseAuthPlugin.m上出现了构建错误：不兼容的块指针

/Users/sergebesnard/Development/flutter/.pub-cache/hosted/pub.dartlang.org/
firebase_auth-0.5.9/ios/Classes/FirebaseAuthPlugin.m:69:53:
Incompatible block pointer types sending 'void (^)(FIRUser *__strong, NSError *__strong)' to parameter of type 'FIRAuthDataResultCallback _Nullable' (aka 'void (^)(FIRAuthDataResult * _Nullable __strong, NSError * _Nullable __strong)')

在我的笔记本电脑上，代码构建顺利，唯一的区别是测试版，0.3.1并安装了android工具链。

Podfile是一样的：

我坦率地不想在我的工作设置上测试升级颤动sdk，我仍然需要处理那些东西......

我不知道这是否有用，但在设置过程中，我遇到了在XCODE上安装颤动的问题，因为当时XCODE没有完全设置。 颤动的医生确实要求我安装包六，并因为python @ 2版本中的冲突而出现问题，所以我强制通过brew python @ 2卸载并重新安装它，然后可以通过`pip install six``安装

如果这是原因，我将不得不重新安装XCODE＆amp;扑。希望不是这样。

答案 0 :(得分：7)

更新cocoapods的存储库。

pod repo update

然后删除Podfile，Podfile.lock，Pos目录，.flutter-plugins，.packages，pubspec.lock

答案 1 :(得分：0)

这是我的提示。只需将cocoapods升级到1.5.3+。我通过brew安装可可豆。

检查可可豆的版本 pod --version

升级 brew upgrade cocoapods

如果遇到错误冲突，请链接 brew link --overwrite cocoapods

再次安装Pod pod install
