解决方法

山姆的评论是正确的。 XCode 的 ruby​​ 框架已损坏。一种解决方法是建立一个符号链接：

cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0
ln -sf universal-darwin20 universal-darwin19

通过这个，我能够成功构建所有原生扩展。

注意：您应该根据您本地的 Xcode SDK 安装更改您的路径段 MacOSX11.1.sdk。

我在使用其他宝石时遇到了同样的问题；我发现了

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin19/ruby/config.h

不存在，但是

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin20/ruby/config.h

存在-即universal-darwin20而不是universal-darwin19。

如果我使用较新版本的Ruby运行安装命令，则它可以正常工作。

对于不同的设置，确切的执行方法将有所不同。我使用的是rbenv，所以在安装命令之前先运行rbenv local 2.6.6。

您可以阅读有关运行多个Ruby版本here的更多信息，也可以只运行一个Ruby版本，但尝试将其升级到较新的版本（例如，brew upgrade ruby，如果您使用的是Homebrew）。

cd 路径就像你的日志错误 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0

复制并重命名文件夹副本 universal-darwin20 到 universal-darwin19

现在可以使用了。
您可以尝试更高版本的 ruby​​ 或 rails。对它的 gem 支持
