无法安装cocoapods - 安装cocoapods时出错：错误：无法构建gem本机扩展

Question

我正在尝试使用以下命令安装cocoapods：

sudo gem install cocoapods

我尝试过更新 ruby、卸载并重新安装 ruby，这样我就可以安装 cocoapods

这是我的错误：

Building native extensions. This could take a while...
ERROR:  Error installing cocoapods:
    ERROR: Failed to build gem native extension.

1. sudo gem update —system

   我尝试运行这个来更新。

2. xcode-select --install

   ，也尝试过这个，因为我看到有人说这对他们有用。这也行不通。

有人遇到过这个问题吗？你是如何解决的？

更新 - 我如何解决这个问题：

• 在

  mkmf.log

  中，您将找到您应该拥有的universal-darwinxx 文件。就我而言，是

  /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin21

• 运行此命令

  cd $(xcode-select -p)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0

  以确认您当前拥有哪些文件。我发现我有

  universal-darwin22

• 确认您有不同的文件后，运行此命令

  sudo ln -sf universal-darwin22 universal-darwin21

  。此命令创建一个名为

  universal-darwin21

  的符号链接，指向

  universal-darwin22

  。

• 这应该可以解决问题。现在，当您再次运行命令

  sudo gem install cocoapods

  时，您应该能够毫无问题地安装它
