运行pod install时出错:如何解决此问题



我搜索了很多，但遗憾的是没有找到解决方案。对于我的flutter项目，我在pubspec.yaml文件中添加了Firebase插件，从那以后，我再也无法在iPhone上运行该项目了。

上面写着：异常：运行pod安装时出错

到目前为止我尝试过的：删除podfile并运行pod install--repo-update，但不起作用。有人能帮帮我吗？非常感谢！

这是我的终端在我尝试运行项目时显示的内容：

Exception: Error running pod install
Exited (sigterm)

在M1Mac上，这是一个已知的问题。这是你应该做的。

  1. 运行此命令(只需要第一次运行(
sudo arch -x86_64 gem install ffi
  1. 这样安装你的pod
arch -x86_64 pod install

接下来，您只需要运行第二个命令来安装pod。

来源1：尝试pod安装#10220 时出错

来源2：pod install/w m1 macbook#10518

如果你不想每次运行pod install时都记得包含arch -x86_64，我在苹果的论坛上找到了一个对我有用的替代答案：

  1. 卸载CocoaPods(如果由gem安装(
$ [sudo] gem uninstall cocoapods     # use sudo if cocoapods was installed using sudo
  1. 使用Homebrew安装CocoaPods
$ brew install cocoapods
  1. 使用常规命令安装pod
$ pod install

安装吊舱就像是CocoaPods的自制版本的魅力！

这个答案可能不适合所有人；CocoaPods的网站并没有正式建议使用Homebrew进行安装，也不是每个人都使用Homebrew。但我喜欢Homebrew，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。

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，打开Podfile。

如果有如下代码：

#platform :ios, '9.0'

删除#字符并将9.0更改为10.0，最后的代码应该是这个

platform :ios, '10.0'
