ruby - 无法在 Windows 机器中安装 rmagick

Question

我是 rmagick 和 ruby​​ 的新手。我使用的是 ruby​​ 1.8.6 版本

实际上我下载了 rmagic2.9.0 win32 版本并解压并安装了 imageMagic-6.4.8。然后在命令提示符下我给了 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

然后尝试给予

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

*** REMOTE GEMS ***

然后

我无法安装 rmagick。谁能帮我解决这个问题？提前致谢。

你的问题在这里:

C:>gem install rmagick --local ERROR: could not find gem rmagick locally or in a repository

该命令必须从您解压缩 rmagick-win32 下载的目录运行。否则，gem 将无法找到它。
