Python 3.x Python Wand缺少库/路径

我正在尝试安装Python3的Wand，对我来说，可以通过我的Cygwin安装访问它

我首先尝试安装魔杖：

# Install Wand
#--------------
# https://docs.wand-py.org/en/0.6.6/guide/install.html
$ python -m pip install Wand
Defaulting to user installation because normal site-packages is not writeable
Collecting Wand

Successfully installed Wand-0.6.6
WARNING: You are using pip version 21.0; however, version 21.0.1 is available.
You should consider upgrading via the '/bin/python -m pip install --upgrade pip' command.

然后我尝试导入图像，但出现错误：

# Try importing from Wand
#------------------------
# https://docs.wand-py.org/en/0.6.6/guide/read.html#open-an-image-file
$ python
>>> from wand.image import Image
Traceback (most recent call last):
  File "/home/User.Name/.local/lib/python3.8/site-packages/wand/api.py", line 151, in <module>
    libraries = load_library()

    raise IOError('cannot find library; tried paths: ' + repr(tried_paths))
OSError: cannot find library; tried paths: []

During handling of the above exception, another exception occurred:

  File "<stdin>", line 1, in <module>
  File "/home/User.Name/.local/lib/python3.8/site-packages/wand/image.py", line 18, in <module>

  File "/home/User.Name/.local/lib/python3.8/site-packages/wand/api.py", line 175, in <module>
    raise ImportError('MagickWand shared library not found.\n'
ImportError: MagickWand shared library not found.
You probably had not installed ImageMagick library.

已确认的魔杖安装：

已确认

sys.path

包含

~/.local/lib/python3.8/站点包

：

$ python
>>> import sys
>>> for path in sys.path:
...    print(path)
... 

/usr/lib/python38.zip
/usr/lib/python3.8
/usr/lib/python3.8/lib-dynload

检查系统上的python版本是32位还是64位。如果您有32位版本，请尝试安装64位版本，然后检查。

我的Cygwin安装是64位的，因此所有

ImageMagick

和

MagickWand

库也是64位的。

pip

不会寻找64位

魔杖吗？我如何确定安装的
pip
-棒
是否为64位？

>>> import sys
>>> for path in sys.path:
...    print(path)
