我针对这个问题进行了研究,在我的电脑上已经花费数小时来解决它。
大约3周前,我在桌面计算机上安装了RMagick,但过程相当复杂。
我不记得我采取的确切步骤,我真的很沮丧。
我将ImageMagick安装到了C:\ImageMagick目录下。
我还为Ruby安装了开发工具包。
我把rmagick-rmagick-v2-2-g564f157放入了正确的gems文件夹中,在我的C:盘里,路径为C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems。
我遇到了以下错误:
我会键入:gem install rmagick -- '--with-opt-dir="c:\ImageMagick"'
然后会得到以下错误:
Temporarily enhancing PATH to include DevKit...
Building native extensions with: '--with-opt-dir="c:\ImageMagick"'
This could take a while...
ERROR: Error installing rmagick:

我现在感到非常沮丧。它在我的台式电脑上可以工作,但在这里却无法运行。有什么建议吗?
