我正在尝试使用PDFPlumber库，它使用Wand的图像格式。但是，当尝试运行:
时from wand.image import Image
我得到这个错误:

During handling of the above exception, another exception occurred:

'Try to install:n ' + msg)
ImportError: MagickWand shared library not found.
You probably had not installed ImageMagick library.
Try to install:
brew install freetype imagemagick
我第一次尝试正常安装:
pip3 install wand
brew install imagemagick
然后，我尝试使用这里列出的方法，并尝试了以下方法:
pip3 install wand
brew uninstall imagemagick
brew install imagemagick@6
brew unlink imagemagick && brew link imagemagick@6
export MAGICK_HOME="/opt/homebrew/opt/imagemagick@6/"
export PATH="/opt/homebrew/opt/imagemagick@6/bin:$PATH"
但是我仍然得到相同的错误。
我也尝试了这里列出的解决方案，并确认我正在运行这里提到的64位python 3.7。我该如何解决这个问题?我特别困惑，因为运行后:
cd /opt/homebrew/opt/imagemagick@6/lib
ls
我可以看到/opt/homebrew/opt/imagemagick@6/lib/libMagickWand-6.Q16.dylib是Wand期望的位置(在上面错误中的尝试路径中列出):
ImageMagick libMagickCore-6.Q16.7.dylib libMagickWand-6.Q16.a
libMagick++-6.Q16.9.dylib libMagickCore-6.Q16.a libMagickWand-6.Q16.dylib
libMagick++-6.Q16.a libMagickCore-6.Q16.dylib libMagickWand-6.Q16.la
libMagick++-6.Q16.dylib libMagickCore-6.Q16.la pkgconfig
libMagick++-6.Q16.la libMagickWand-6.Q16.7.dylib
当我尝试在M1 mac上运行Wand时，我遇到了同样的问题，尽管相同的步骤在x86系统上工作。对我来说有效的解决方案是在x86模式下通过brew安装ImageMagick:
alias brew86="arch -x86_64 /usr/local/bin/brew"
brew86 install imagemagick
# get imagemagick installation path
brew86 info imagemagick
export MAGICK_HOME=/usr/local/Cellar/imagemagick/7.1.0-49_1
export PATH="$MAGICK_HOME/bin:$PATH"
我在Mac M1机器上也面临同样的问题。我只设置了ENV变量检查完brew info imagemagick命令后，如下所示。没有必要重新安装imagemigick为arch -x86_64，至少对我来说，在Mac M1操作系统Monterey 12.6
出口MAGICK_HOME =/opt/组装/地窖/imagemagick/7.1.0-51导出路径="MAGICK_HOME美元/bin: PATH"美元;
和它工作良好。
