我对rmagick和ruby都不熟悉。我正在使用1.8.6版本的ruby。
实际上，我下载了rmagic2.9.0 win32版本并解压缩安装了imageMagic-6.4.8。然后我在命令提示符中输入了gem update --system。
C:\>gem update --system
Updating RubyGems
Nothing to update
然后
C:\>gem install rmagick --local
ERROR: could not find gem rmagick locally or in a repository
然后尝试给出。
C:\>gem list --remote --all rmagick
