我使用了 ruby​​ 1.9.2 和 rails 3.0.3。我正在尝试安装 rmagick gem，但是当我运行 bundle install 时，我收到一条错误消息:

我从 http://rubyinstaller.org/downloads/ 安装了 ruby带有开发工具包和最新版本的 ImageMagick。我尝试设置 rmagick 配置(lib 和 include 目录)但我仍然遇到相同的错误

有什么帮助吗？有解决问题的想法吗？

最佳答案

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:
*重要提示:安装路径不能包含任何空格。
理想情况下选择“C:\ImageMagick”

请确保选择以下选项:

Add application directory to your path system
Install development headers and libraries for C and C++

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
