【问题描述】：
我整天都在学习教程，试图安装 RMagick，现在我估计已经走了很远，但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:
ERROR: Failed to build gem native extension.

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.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include

我认为粗体部分是重要的部分，我做了一些研究，知道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：
检查 Ruby 版本 >= 1.8.5... -------------------- 是

2:
3: #include <winsock2.h>
4: #include <windows.h>

/* end */
有人有什么想法吗？
非常感谢您的帮助！
问候，埃米尔
