我正在尝试在 Ubuntu 10.04 LTS 上安装 refinerycms，这是一个 Ruby on Rails CMS。我运行 rails server 并得到以下异常：

carcher@carcher-laptop:~/Code/tgc$ rails server

我按照here 的说明从源代码构建并安装了 ImageMagick 6.6.4，在此之前我删除了预装在 Ubuntu 中的 ImageMagick 工具，以避免任何冲突。但我似乎仍然有这个版本 6.5.7。

我想我的问题是如何删除/禁用ImageMagick 6.5.7-8？

提前感谢您的帮助，我完全没有想法。

干杯，夏兰。

【解决方案1】：

在 Refinery Google 小组有很多帮助：http://groups.google.com/group/refinery-cms。还是您已经尝试过？

【讨论】：

我会在那里尝试 - 认为这是一个更普遍的问题，所以在这里发布。谢谢。

【解决方案2】：

我开始跑步了！我做了一个干净的 Ubuntu 安装，并且只使用了预安装的 Imagemagick 包。 Lunix 的Refinery CMS tutorial 省略了像我这样的新手需要做的一些事情，所以我记录了我的所有步骤here。

主要问题是，在此过程的早期，当我遇到 RMagick 问题时，我认为我需要更高版本的 Imagemagick，因此我从源代码下载并安装了它。没有必要这样做——根本没有。版本 6.5.7-8 可以很好地与 RMagick 和 RefineryCMS 配合使用。

希望这对其他人有所帮助。

如果您需要使用最新版本，那么我发现这篇文章可能会有所帮助。不过我还没试过：

我 posted 这个信息也在 RefineryCMS Google 留言板上。

干杯，夏兰
