我按照说明从源代码构建并安装了 ImageMagick 6.6.4这里在此之前，我删除了 Ubuntu 中预装的 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？
答案1
如果您在软件包列表中找不到 imagemagick 6.5.7，则可能是您将其安装到了 /usr/local。
尝试which convert查看 imagemagick 二进制文件的位置。（convert是 imagemagick 附带的实用程序之一。）还尝试convert --version查看哪个版本处于活动状态。如果您获得的版本与 Ruby/Rails 看到的版本不同，请检查您的项目配置以确保您没有它可能正在查找的任何额外路径。此外，请确保 imagemagick 未安装到您的 Rails 应用程序目录中；我认为它也可能尝试在那里包含内容。

我已经启动并运行！解决方案已发布这里在 Stack Overflow 上。
