Intalling pycairo with Python 3.7 on Windows

问题

I'm trying to install pycairo, and in spite of what I found on the Internet, I don't manage to to it

I did pip install pycairo, but it askek me to install Visual Basic Build Tool. I did it but it doesn't work then. I tried a lot of ideas found on the web (e.g. with this website https://www.lfd.uci.edu/~gohlke/pythonlibs/), but it also didn't work.

When I try pip install pycairo, the error message is :

And I don't understant it !

回答1:

installing libraries can be a little tough on Windows. I usually use this website : https://www.lfd.uci.edu/~gohlke/pythonlibs/

Then, search for your package (here : pycairo‑1.18.1‑cp37‑cp37m‑win_amd64.whl)

Then, you launch cmd in the folder where you downloaded the file, and execute :

pip install pycairo‑1.18.1‑cp37‑cp37m‑win_amd64.whl

I hope this will help you !
