我无法在windows上安装rmagick gem

Question

我使用的是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，我得到一个错误提示：

我用开发包和最新版本的ImageMagick安装了来自http://rubyinstaller.org/downloads/的ruby。我尝试设置rmagick配置(lib和include目录)，但仍然收到相同的错误

有什么帮助吗？有什么想法来解决这个问题吗？

Answer 1

前提条件：

Ruby > 1.8.6

DevKit (任何版本)

没有其他ImageMagick安装或路径条目

步骤1: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：

将应用程序目录添加到path系统

安装C和C++的开发头和库

步骤2: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

我有the same problem，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
ImageMagick-6.8.8-2-Q8-x64-static.exe

在将ImageMagick从v6.8.8重新安装到6.6.7之后，我成功地安装了rmagik gem。这只是一个不兼容版本的问题...

Answer 3

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

请看一下：http://rmagick.rubyforge.org/install-faq.html#win
