Question

我知道有很多关于此错误的问题，但我在没有找到解决方案的情况下阅读了几个教程和SO讨论。

我正在尝试安装rmagick（我想为Ruby on Rails安装Spree电子商务，需要ImageMagick和rmagick）。

我正在使用Windows 7（64位），Ruby版本是：2.1.5，Rails版本是4.2.1。我下载并安装了（在C：\ ImageMagick中）ImageMagick-6.9.1-2-Q16-x64-dll.exe，我还安装了Dev-Kit。

我按照Sumit Munot在此提出的步骤ImageMagick Install Windows，但是当我按照步骤6进行操作时，我得到了这个错误。

这是我的路径：C:\RailsInstaller\Git\cmd;C:\RailsInstaller\Ruby2.1.0\bin;C:\Ruby21\bin; 我是否必须在路径中添加一些东西？
