命令

find /usr/local /opt/homebrew -name "MagickWand.h"

问题

/opt/homebrew/Cellar/imagemagick@6/6.9.13-4/include/ImageMagick-6/wand/MagickWand.h
/opt/homebrew/Cellar/imagemagick/7.1.1-26/include/ImageMagick-7/MagickWand/MagickWand.h

我试过了

brew install imagemagick@6 && brew link imagemagick@6 --force
export LDFLAGS="-L/usr/local/opt/imagemagick@6/lib"
export CPPFLAGS="-I/usr/local/opt/imagemagick@6/include"
export PKG_CONFIG_PATH="/usr/local/opt/imagemagick@6/lib/pkgconfig"
brew uninstall pkg-config && brew install pkg-config
PKG_CONFIG_PATH=/usr/local/opt/imagemagick@6/lib/pkgconfig gem install rmagick -v '2.16.0'

等等

我尝试了所有stackoverflow等，尝试重新安装所有依赖库，我还重新安装了Ruby 2.6.5，使用rbenv，我陷入了死胡同，请帮助我，好人

看起来

MagickWand.h

头文件丢失了。 您可以检查

mkmf.log

文件以获取更多详细信息，但这里有一些可以尝试的方法，这些方法是导致此类问题的常见原因：

1. 由于您已经在系统上找到了

   MagickWand.h

   ，因此它可能已安装，但可能无法正确链接。

brew install imagemagick@6
brew link imagemagick@6 --force

2. 您已经设置了 PKG_CONFIG_PATH 环境变量，但请确保它指向 ImageMagick 的正确版本

export PKG_CONFIG_PATH="/usr/local/opt/imagemagick@6/lib/pkgconfig"

3. 有时，明确告诉 gem 在哪里可以找到

   MagickWand.h

   会有所帮助

gem install rmagick -v '2.16.0' -- --with-magick-wand-include="/usr/local/opt/imagemagick@6/include/ImageMagick-6/wand"

如果这些都不起作用，您可以尝试卸载并重新安装 imagemagick 和 rmagick。 还要确保您没有安装多个版本。这有时会导致冲突。 我能想到的最后一件事就是尝试卸载并重新安装 ruby，并确保您的 macOS 是最新的，因为它有时会导致问题。
