我正在尝试将 puma 安装到我的 MacOS 10.13.6 上。要安装 puma，我运行命令gem install puma但它回来了

To see why this extension failed to compile, please check the mkmf.log which can be found here:

我的 Mac 上安装了 Xcode。我运行了 xcode-select --install 确认 Xcode 已经安装。
然后我认为这可能是权限问题......
~ $ ls -lah tmp
total 0
drwxrwxrwx 3 salem staff 96B Jul 30 08:35 .
drwxr-xr-x+ 62 salem staff 1.9K Aug 1 13:17 ..
drwxr-xr-x 3 salem staff 96B Jul 27 15:11 vmSWVyg
但它似乎设置了正确的权限。
安装 nokugiri 时也会出现此问题
您可能想要安装 openssl，例如通过自制软件：
brew install openssl
类似的问题也被讨论过github https://github.com/puma/puma/issues/783.
如果是 nokogiri，libxml 可能会丢失：
brew install libxml2
