我一直在尝试使用Macports在Mac上安装poppler，因为它是对其他东西的依赖。我运气不好。我已经为有同样问题的人进行了多次讨论，但解决方案并不能解决问题。如果你能推测出这里出了什么问题，请提前感谢！
我的详细信息：
- MacBook Pro(13英寸，2017，四个Thunderbolt 3端口(
- MacOSX Big Sur(11.2.3版(20D91((
- XCode版本12.4(12D4e(
这是我运行端口安装时的输出：
Warning: The macOS 11.2 SDK does not appear to be installed. Ports may not build correctly.
Warning: You can install it as part of the Xcode Command Line Tools package by running `xcode-select --install'.

我无法更新SDK以消除该警告
