在pkg-config的搜索路径中未找到MagickCore包。

我试图安装rmagick，但它总是提示未配置PKG_CONFIG_PATH。

这种情况多次发生在我身上，所以我将其发布为一个问题，并为任何遇到相同问题的人提供答案。

在 macOS 上安装 ImageMagick，命令为 brew install imagemagick。参考链接为 https://dev59.com/EWkw5IYBdhLWcg3wMHyn。 - Jeremy Cochoy

根据你的rmagick版本，你可能需要安装imagemagick v6： brew install imagemagick@6 && brew link imagemagick@6 --force - Capripot

我也遇到了同样的问题。这个方法对我有用（在Ubuntu上）：

sudo apt-get install libmagickwand-dev

rmagick gem 在安装时无法找到 PKG_CONFIG_PATH。我们需要告诉它 ImageMagick 的路径在哪里。最好将其添加到 bash 中。

export PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.9.3-7/lib/pkgconfig

这对我解决了问题（在Ubuntu 18.04上有效）：

sudo apt-get install libmagick++-dev
这对我来说起作用了，针对相关的“在 pkg-config 搜索路径中未找到包 Magick++”错误。 - Scriddie
