Question

我刚刚从Windows 10切换到Mac。我已经发布了Flutter应用程序的Android版本。现在，我正在开发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，出现错误提示。

Answer 1

我通过运行手动的“ pod update”和Flutter的“ Packages get”来解决了此问题……

在终端更改目录中：

cd FLUTTER_PROJECT_FOLDER_PATH/ios

运行pod更新：

pod update

运行Flutter软件包获取

// In Android Studio, open 'pub spec.yaml', press 'Packages get'

然后您应该可以构建到iOS
第一次构建的时间比正常时间长约3分钟，但随后的构建又恢复了正常。

Answer 2

我通过清洁和重新安装 Pod 解决了这个问题。

首先，保存并退出 Xcode。

在终端：

cd 到目录
<块引用>
吊舱解体
<块引用>
豆荚清洁
<块引用>
pod 安装

（这将需要几分钟）

重新打开 xcworkspace。

那么它应该可以工作。（第一次构建需要几分钟。）

Cocapods找不到Pod Firebase的兼容版本
