运行 pod install 时出错：如何解决此问题？

Question

我进行了很多搜索，但不幸的是我没有找到解决方案。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。

它说：异常：运行 pod install 时出错

到目前为止我尝试过的：删除 podfile 并运行 pod install --repo-update 但它不起作用。有人可以帮帮我吗？非常感谢！

这是我尝试运行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。

运行此命令（只需第一次运行）

sudo arch -x86_64 gem install ffi

像这样安装你的 pod。

arch -x86_64 pod install

接下来，您只需运行第二个命令即可安装 pod。

来源 1：尝试 pod install #10220 时出现错误

来源 2：pod install /w m1 macbook #10518

Answer 2

如果您不想每次运行

arch -x86_64

时都必须记住包含

pod install

，我在 Apple 论坛中找到了一个对我有用的替代答案：

卸载 CocoaPods（如果通过 gem 安装）

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

使用 Homebrew

$ brew install cocoapods

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，而且并不是每个人都使用 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发现这个。

Answer 3

在终端上运行此代码

sudo arch -x86_64 gem install ffi

接下来，转到项目中的 ios 文件夹，然后打开 Podfile。

如果有如下代码：

#platform :ios, '9.0'

去掉

字符，将

9.0

改为

10.0

，最终代码应该是这样的

platform :ios, '10.0'

Answer 4

这对我有用：

这需要更多代码才能完全工作：

在终端应用程序中：

第 1 步：（如果适用）。

sudo gem uninstall cocoapods

第 2 步：此命令将使用 Homebrew 安装 CocoaPods 以及任何所需的依赖项，而不直接涉及 Ruby gem。

brew install cocoapods

第 3 步：验证 CocoaPods 是否已正确安装。

pod --version

注意：如果您在第 3 步遇到像我一样的错误，请继续下一步：

第 4 步：有时，即使安装后，二进制文件也可能无法正确链接。您可以确保它们通过以下方式链接。

brew link --overwrite cocoapods

第 5 步：验证 CocoaPods 是否已正确安装。

pod --version

希望这对其他人也有帮助！干杯！
