我正在尝试使用以下命令安装RmMagic:
gem install rmagick -v=2.12.2
运行此命令后,我收到一些错误:
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing rmagick:
ERROR: Failed to build gem native extension.

Invalid drive specification.
Unable to get ImageMagick version
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=D:/ruby/bin/ruby
Gem files will remain installed in D:/ruby/lib/ruby/gems/1.8/gems/rmagick-2
.12.2 for inspection.
Results logged to D:/ruby/lib/ruby/gems/1.8/gems/rmagick-2.12.2/ext/RMagick

请帮助我这方面 . 提前致谢 .

我有同样的问题与rmagick解决这个添加系统环境变量
然后做
这是多么痛苦......我绝对需要同时执行系统环境变量和Mukesh建议的命令的特定语法
澄清这两个步骤:(对于像我这样的其他新手)
单击“计算机”上下文菜单中的属性,单击“高级系统设置”,单击“环境变量”,单击“系统变量”下的“新建”,
使用CLASSPATH作为变量名和值使用:
.;C:\ImageMagick-6.9.0-Q16\include;lib C:\ImageMagick-6.9.0-Q16\lib
然后使用Ruby终端以管理员身份运行命令提示符并执行:
gem install rmagick -v '2.13.4' -- --with-opt-lib=C:\ImageMagick-6.9.0-Q16\lib --with-opt-include=C:\ImageMagick-6.9.0-Q16\include
(***确保在必要时更新Variable和gem命令中的版本号)
