我整天都在研究教程，试图安装 RMagick，现在我估计已经走得很远了，但是偶然发现了一个我真的不知道如何解决的错误，也没有得到任何有用的信息。
当我尝试安装 gem 时，我收到以下消息：
Building native extensions. This could take a while...
ERROR: Error installing rmagick:

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

我想粗体部分是重要的部分，我做了一些研究并且明白 stdint.h 是某种头文件，但我不知道如何安装它。
我还检查了 mkmf.log 文件，它为我提供了一些易于阅读的信息：

有人有想法么？
非常感谢您的帮助！
