RMagick不工作

我很感激你的帮助-我相信这是个简单的错误。

C:\sanj\rubyjobs . 我已在默认位置成功安装ImageMagick: C:\Program Files (x86)\ImageMagick .

我还通过运行 gem install rmagick --local 在里面 C:\sanj\rubyjobs\vendor\RMagick Extract

跑步时 bundle install ,我得到以下错误:

C:/Sanj/Ruby192/bin/ruby.exe extconf.rb  
checking for Ruby version >= 1.8.5... yes  
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

当我跑的时候 identify -version 从ruby命令提示符,我得到: http://www.imagemagick.org 版权所有:版权所有(C)1999-2009 ImageMagick Studio LLC

如果安装了ImageMagick并且提示找到了它,为什么它说它无法获得版本??
