我正在尝试使用PDFPlumber库，它使用Wand的图像格式。然而，在试图运行时：

from wand.image import Image

我知道这个错误：

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/wand/api.py", line 177, in <module>
'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，我尝试使用列出的这里方法，并尝试如下：

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"

但还是会犯同样的错误。

我还尝试了列出的解决方案这里，并确认我正在运行64位python3.7，正如提到的这里。我怎么才能解决这个问题？我特别困惑，因为在跑步之后：

cd /opt/homebrew/opt/imagemagick@6/lib
ls

我可以看到，/opt/homebrew/opt/imagemagick@6/lib/libMagickWand-6.Q16.dylib正是Wand期望它出现的地方(在上面错误中的尝试路径中列出)：

 ImageMagick                     libMagickCore-6.Q16.7.dylib     libMagickWand-6.Q16.a

当我尝试在M1 mac上运行魔杖时，我也面临着同样的问题，尽管相同的步骤在x86系统上是有效的。对我来说有效的解决方案是在x86模式下通过brew安装x86：

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"
