C:\Users\a>

It seems that the installer is trying to reach a file named "hunspell.h" which can not be found.

I tried to put the file I found at dxr.mozilla.org in "C:\Users\a\AppData\Local\Programs\Python\Python35-32\include". Then I got a similar error about hunvisapi.h. Created that, too. Now I'm getting LINK : fatal error LNK1181: cannot open input file 'hunspell.lib'. I don't know where I can find this one yet; but there must be an easier way to do all this.

In short, how can I install hunspell without getting the errors above?

Your problem is that pyhunspell is a binding to the C (coded using C Python API) hunspell library, thus it needs to compile. To compile it needs to have hunspell installed and access to hunspell header files of the core hunspell program.

The part with the header files you managed to tweak it but you need hunspell installed on your computer. For that see here or here.

Once it's done you can retry pip install or you can try precompiled package there is only one available but it might work (see http://pyhunspell.latinier.fr/)

Hope it helps.

See this answer:

On Ubuntu:

# installing gcc if not already installed
sudo apt install build-essentials

# installing CyHunspell, which is currently maintained (see link to answer)
pip install cyhunspell

# now you can
import hunspell
# and do your stuff

pip install hunspell: Cannot open include file: 'hunspell.h': No such file or directory
