Question

我一整天都在努力安装RMagick教程，现在我觉得已经相当远了，但是我发现了一个错误，我真的不知道如何解决，也没有得到任何有用的信息。

当我尝试安装gem时，我收到此消息：

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick:
 ERROR: Failed to build gem native extension.

我认为粗体部分是重要的部分，我做了一些研究，并且已经了解stdint.h是某种标题，但我不知道如何安装它。

我还检查了mkmf.log文件，它给了我这个易于阅读的信息：

/* end */

有人有什么想法吗？

非常感谢您的帮助！

问候，埃米尔

Answer 1

我通过运行安装ImageMagicks devkit的'apt-get install libmagick9-dev'来解决这个问题。

Answer 2

试试这个：

sudo apt-get install libmagickwand-dev

适用于Ubuntu。

你在窗户上吗？如果你是的话，你可能需要安装http://rubyforge.org/frs/?group_id=167＆lt; - 开发工具包，因为一些编译命令不存在......
