推荐答案

根据错误：

extconf.rb:171:in ``': No such file or directory - convert -version
(Errno::ENOENT)

您似乎没有安装Imagemagick（或同等产品）。 Imagemagick套件中的主要应用程序是 convert 二进制文件。如果你确定做安装了它，那么你应该检查它是否可以在 PATH 中访问。

it would appear that you don't have Imagemagick (or an equivalent) installed. The main application in the Imagemagick suite is the convert binary. If you're certain you do have it installed, then you should check that it's accessible in the PATH.
