Answer 1

日志文件指出错误：Can't find Magick-config in [PATH]。

所以在你的文件系统上找到Magick-config 文件并将它放在你的路径中，例如通过运行

locate Magick-config

对我来说返回：

/usr/local/Cellar/imagemagick@6/6.9.9-34/bin/Magick-config

如果您在任何地方都找不到Magick-config 文件，请找出为什么没有。

即使您克服了该错误，您仍然无法让 rmagick 工作，因为尚不支持 ImageMagick 7。 相关 Github 问题：

• https://github.com/rmagick/rmagick/issues/256
• https://github.com/rmagick/rmagick/issues/265
• https://github.com/rmagick/rmagick/issues/271

还有另一个 StackOverflow 答案，解释了如何让它工作：ImageMagick 7 with RMagick 2.16 on MacOS Sierra Can't find MagickWand.h
