Error running pod install: How to solve this problem?

Question

我进行了很多搜索，但不幸的是我没有找到解决方案。\n对于我的 flutter 项目，我在 pubspec.yaml 文件中添加了 Firebase 插件，从那时起我就无法再在我的 iPhone 上运行该项目了。

\n

它说：Exception: Error running pod install

\n

到目前为止我尝试过的：删除 podfile 并运行pod install --repo-update but it didn't work.\nCan someone PLEASE help me? Thank you so much!

\n

这是我尝试运行该项目时终端显示的内容：

Answer 1

在M1 Mac 上，这是一个已知问题。这是你应该做的。

1. 运行此命令（只需第一次运行）

sudo arch -x86_64 gem install ffi

2. 像这样安装你的 pod。

arch -x86_64 pod install

展望未来，您只需运行第二个命令即可安装 pod。

来源 1：尝试 pod install 时出错 #10220

来源 2：pod install /w m1 macbook #10518

Answer 2

如果你不想arch -x86_64每次运行时都记住包含pod install，我在苹果论坛中找到了一个对我有用的替代答案：

1. 卸载 CocoaPods（如果通过 gem 安装）

$ [sudo] gem uninstall cocoapods     # use sudo if cocoapods was installed using sudo

2. 使用Homebrew安装 CocoaPods

$ brew install cocoapods

3. 使用普通命令安装 pod！

$ pod install

使用 Homebrew 版本的 CocoaPods 安装 Pod 简直太神奇了！

这个答案可能并不适合所有人；CocoaPods 的网站并没有正式推荐使用 Homebrew 来安装，而且并不是所有人都使用 Homebrew。但我喜欢 Homebrew，而且我发现这比更改安装 pod 的命令要容易得多。这个答案最初归功于treekie_，但在这里分享以防其他人首先找到这个答案。
