ImportError: The 'enchant' C library was not found. Please install it via your OS package manager, or use a pre-built binary wheel from PyPI

On Ubuntu, run sudo apt-get install libenchant1c2a

Resolved: On Win7-64 I ran

pip3 install pyenchant==1.6.6

which seems to be the latest version of PyEnchant that still shipped with Win-64 binaries. Newer versions did not install for me, but this one did.

I found the answer in this GitHub page.

In a nutshell, they have not shipped a wheel for the win_amd64 platform yet.
