xcode - Flutter 项目无法在 Mac M1 上构建

Question

我最近买了一本带有 M1 的新 Mac 书。芯片并在构建中面临 Flutter 和 Firebase 之间的巨大问题。我会同时列出 Flutter 错误日志和 Xcode 错误日志。

注意:我正在 Flutter channel Master

上构建

Flutter 错误日志:

    Launching lib/main.dart on iPod touch (7th generation) in debug mode...

这是主要错误，有很多警告，但我不确定它们是否导致构建失败。

运行 flutter doctor 结果:

Answer 1

我们知道 m1 mac 运行在基于 arm 的处理器上，因此很少有像 cocoa pods 和 ffi 这样的东西需要在此基础上构建。经过长时间的研究，我想出了几个步骤，每次你坚持为 m1 mac 构建 xcode Flutter 应用程序时，这些步骤肯定会有所帮助。

要在带有 M1 芯片(Apple Silicon)的 Mac 上完全安装 cocoapods，请按照以下步骤操作:

在 M1 中安装 Cocoa Pods

• sudo gem 安装 cocoapods
• sudo gem 安装 ffi
• arch -x86_64 sudo gem install cocoapods -n/usr/local/bin
• sudo gem install cocoapods -n/usr/local/bin

安装 ffi

• sudo arch -x86_64 gem install ffi

#update repo

• arch -x86_64 pod install --repo-update

Flutter iOS 构建

• 干净利落
• flutter 构建 ios

在flutter项目的iOS文件夹中重新安装依赖

• arch -x86_64 pod 安装
