如果您正在使用Homebrew，则建议的方法是告诉pkg-config可在哪里找到libxml2库：

brew reinstall libxml2
export PKG_CONFIG_PATH="/usr/local/opt/libxml2/lib/pkgconfig"

- codenamev

我既沒有找到被接受的答案也沒有從這個答案中得到幫助。我通過在 https://github.com/twilio/twilio-ruby/issues/315#issuecomment-453697013 上提供的命令來解決問題。 - Vishal

这对我也起作用了，在Catalina 10.15.2上。谢谢伙计！ - Iuliana Cosmina

此外，您可能拥有过时的捆绑配置，这会妨碍操作。运行bundle config build.nokogiri --use-system-libraries，它将给出一个警告并显示您当前所拥有的配置。我一直在遵循所有指南，并多次重新安装所有宝石甚至是 Ruby，只是发现配置设置为使用一个不再存在的路径。

出现这个错误是由于macOS Mojave停止将标准头文件放置在/usr/include中，而只将它们放在XCode目录中。

您可以通过运行ls /usr/include来验证这一点，最可能的情况是此目录不再存在。相反，通常的解决方法xcode-select --install将无法解决问题。

解决方法是运行由Apple提供的旧版安装程序，该安装程序将把头文件安装到/usr/include中。

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
