我一直在尝试安装win32screenshot gem但收到以下DependencyError：
C:\Ruby200\lib\ruby\gems\2.0.0\gems>gem install mini_magick-4.6.1.gem win32screenshot-2.1.0.gem
Successfully installed mini_magick-4.6.1
Parsing documentation for mini_magick-4.6.1
ERROR: While executing gem ... (Gem::DependencyError)
Unable to resolve dependencies: win32screenshot requires mini_magick (~> 4.3.0)"
非常感谢任何线索。
谢谢， 瓦西
