我使用开发工具包和最新版本的ImageMagick 从http://rubyinstaller.org/downloads/安装了ruby .我试图设置rmagick配置(lib和包含目录),但我仍然得到相同的错误

任何帮助？有什么想法解决这个问题？

Answer 1

先决条件:
Ruby> 1.8.6
DevKit(任何版本)
没有其他ImageMagick安装或PATH条目

第1步:安装ImageMagick:

下载ImageMagick:http: //imagemagick.spd.co.il/binaries/ImageMagick-6.8.0-3-Q16-windows-dll.exe

安装ImageMagick:
*重要:安装路径不应包含任何空格.
理想情况下选择"C:\ ImageMagick"

请务必选择以下选项:

将应用程序目录添加到路径系统
为C和C++安装开发头和库

第2步:安装rmagick:

使用以下命令安装rmagick gem:

gem install rmagick --platform=ruby -- --with-opt-lib=c:/ImageMagick/lib --with-opt-include=c:/ImageMagick/include

Answer 2

使用rmagick-win32 gem，不需要单独使用ImageMagick。这是捆绑的。
