如何为 Windows XP 安装 rmagick gem?我已经安装了带有头文件的 ImageMagick,并安装了 DevKit 附带的 RailsInstaller.org。我不知道在哪里可以解决这些错误。

我也有 Cygwin 并在那里尝试过,但遇到了不同的 ruby​​ 相关错误。我可以看到一些错误,例如“无效的驱动器规格”,但我不知道这是从哪里来的。

RMagic 不适用于 ImageMagic 6.8。我用详细的说明更新了 RMagick Github wiki。

https://github.com/rmagick/rmagick/wiki

在那里我发现了宝石(哈哈),例如

如果 ImageMagick 不是系统路径中的第一个,当 extconf.rb 尝试识别 ImageMagick 版本时,您将收到“无效的驱动器规范”错误。

gem install rmagick -- '--with-opt-dir="[path to ImageMagick]"'

(很明显吧?)

我相信 RMagick 是一个死项目。已经2年没有提交了!

您应该使用 rmagick-win32:

在管理员模式下启动命令提示符。设置 CPATH 和 LIBRARY_PATH 环境变量分别指向 ImageMagick 安装目录的 include 和 lib 子目录(这样 DevKit 会在构建时找到它们)

设置 CPATH=C:\Program Files (x86)\ImageMagick-6.7.9-Q16\include 设置 LIBRARY_PATH=C:\Program Files (x86)\ImageMagick-6.7.9-Q16\lib

然后启动一个新的命令提示符并

宝石安装 rmagick

这对我有用!在http://www.redmine.org/projects/redmine/wiki/HowTo_install_rmagick_gem_on_Windows中查看结果
