I am trying to install Wand for Python 3, which for me is accessed through my Cygwin installation.
I first tried installing Wand:
# 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

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.
I then tried importing Image but got errors:
# 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):

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

During handling of the above exception, another exception occurred:

raise ImportError('MagickWand shared library not found.\n'
ImportError: MagickWand shared library not found.
You probably had not installed ImageMagick library.
Try to install:
https://docs.wand-py.org/en/latest/guide/install.html
The contents of the cited installation page is identical to the installation page I used above.
Can someone please advise on a next step to try?
Thanks.
