I have the same problem, my environment was:

我有同样的问题，我的环境是：

windows XP (x32)
ruby 1.9.3p484 (2013-11-22) [i386-mingw32]
DevKit-tdm-32-4.5.2-20111229-1559-sfx

I install rmagik gem successfully, after reinstalling of ImageMagick from v6.8.8 to 6.6.7. It was just a problem of incompatibility versions...

在将 ImageMagick 从 v6.8.8 重新安装到 6.6.7 后，我成功安装了 rmagik gem。就是版本不兼容的问题...

First of all clear your path environment variables. (This is the main step that people often skip, but very important). This is the main reason for the error you're facing.

首先清除您的路径环境变量。（这是人们经常跳过的主要步骤，但非常重要）。这是您面临的错误的主要原因。

Then install the rails installer (2.0.0) from here : http://railsinstaller.org/en

然后从这里安装 rails 安装程序（2.0.0）：http: //railsinstaller.org/en

It'll set up ruby, rails, and everything else you need. This will also set up your environment path variables for you as well.

它将设置 ruby​​、rails 以及您需要的所有其他内容。这也将为您设置环境路径变量。

Next install imagemagick 6.7.9.9 or lower and while installing check the option to include C headers. Make sure you install it within the rails installer folder.

接下来安装 imagemagick 6.7.9.9 或更低版本，并在安装时选中包含 C 头文件的选项。确保将其安装在 rails 安装程序文件夹中。

Then type this in your command prompt path=c:\RailsInstaller\ImageMagick-6.7.9-Q8;%path%or whatever version you have.

然后在您的命令提示符path=c:\RailsInstaller\ImageMagick-6.7.9-Q8;%path%或您拥有的任何版本中键入它 。

Then type

然后输入

gem install rmagick -- '--with-opt-dir="c:\RailsInstaller\ImageMagick-6.7.9-Q8"'

Finally edit C:\RailsInstaller\Ruby2.0.0\setup_environment.bat to include the path to ImageMagic

最后编辑 C:\RailsInstaller\Ruby2.0.0\setup_environment.bat 以包含 ImageMagic 的路径

At line 25: SET PATH=c:\RailsInstaller\ImageMagick-6.7.9-Q8;or whatever version you have

在第 25 行：SET PATH=c:\RailsInstaller\ImageMagick-6.7.9-Q8;或您拥有的任何版本

Use rmagick-win32gem, and it doesn't need ImageMagick separately. This is bundled.

使用rmagick-win32gem，它不需要单独使用 ImageMagick。这是捆绑的。
