Ruby 无法在Windows计算机中安装rmagick

我对玛吉克和鲁比还不熟悉。我使用的是ruby 1.8.6版本

实际上，我下载了rmagic2.9.0 win32版本并解压缩，然后安装了imageMagic-6.4.8。然后在命令提示符下，我给出了gem update--system

然后

然后尝试给予

C:\>gem list --remote --all rmagick

*** REMOTE GEMS ***

rmagick (2.9.1, 2.9.0, 2.8.0, 2.7.2, 2.7.1, 2.7.0, 2.6.0, 2.5.2, 2.5.1, 2.5.0, 2
.4.0, 2.3.0, 2.2.2, 2.2.0, 2.1.0, 2.0.0, 1.15.17, 1.15.16, 1.15.15, 1.15.14, 1.1
5.13, 1.15.12, 1.15.11, 1.15.10, 1.15.9, 1.15.8, 1.15.7, 1.15.6, 1.15.5, 1.15.4,
 1.15.3, 1.15.2, 1.15.1, 1.15.0, 1.14.1, 1.14.0, 1.13.0, 1.12.0, 1.11.1, 1.11.0,
 1.10.1, 1.10.0, 1.9.3, 1.9.2, 1.9.1, 1.9.0, 1.8.3, 1.8.2, 1.8.1, 1.8.0, 1.7.4,
1.7.3, 1.7.2, 1.7.1)
rmagick4j (0.3.7, 0.3.6, 0.3.5, 0.3.4, 0.3.3, 0.3.2, 0.3.1)

然后

我无法安装rmagick。有谁能帮我解决这个问题吗？ 提前感谢。

您的问题在这里：

C:>gem安装rmagick--本地错误：无法在本地或存储库中找到gem rmagick

该命令必须从解压rmagick-win32下载的目录中运行。否则，gem将无法找到它

从以前卸载任何图像Magick或RMagick gem

从下载rmagick-win32 for windows，该windows具有gem和ImageMagick安装程序

解压缩上面下载的rmagick-win32 zip文件

从zip中提供的安装程序安装ImageMagick，即运行ImageMagick-6.5.6-8-Q8-windows-dll.exe。这将为您安装ImageMagick

安装zip中的rmagic gem，即rmagick-2.12.0-x86-mswin32.gem

C:\>gem install rmagick --local
