Install wand package in Conda on Windows


I am looking for help installing wand as a Conda newbie. I was successful installing and using wand outside of Conda on this machine. I am running ImageMagick-7.0.10-Q16-HDRI system-wide. When I run:

conda install -c conda-forge wand

or

conda install -c conda-forge/label/cf202003 wand

as recommended at conda forge, this is the result:

conda install -c conda-forge/label/cf202003 wand

Solution

  • It turns out that the conda error message is misleading. The wand package at conda-forge is in error. Instead I installed wand through pip:

    conda install pip
    pip install Wand
