如何为
Windows XP安装rmagick gem？我已经使用头文件安装了ImageMagick,并安装了DevKit附带的RailsInstaller.org.我不知道在哪里修复这些错误.

message SUMMARY
这是mkmf.log的内容
checking for Ruby version >= 1.8.5... -------------------- yes --------------------
我也有Cygwin并尝试过,但遇到了不同的ruby相关错误.我可以看到一些错误,比如“无效的驱动器规范”,但我不知道它来自何处.
解决方法
RMagic不适用于ImageMagic 6.8.我更新了RMagick Github wiki并附有详细说明.
https://github.com/rmagick/rmagick/wiki
在那里我发现了宝石(哈哈)等
If ImageMagick isn’t first in your system path,you’ll get an “Invalid
drive specification” error when extconf.rb tries to identify the
ImageMagick version.
和
gem install rmagick -- '--with-opt-dir="[path to ImageMagick]"'
(很明显,是吧？)
我相信RMagick是一个死的项目. 2年没有提交！
