Upon executing pip install manimlib, on windows, the following is seen.

The solution for this is already given in the README.md file, which is to install the wheel for newer version of pycario (1.18.0), but how would that work with pip installation? I tried installing the wheel as given in the instructions, but nevertheless, pip installation fails.

建议将操作系统编码改为 utf-8（默认gbk），我win10改编码后安装成功！

As for jpl860, the wheel that worked for me was “pycairo‑1.18.0‑cp37‑cp37m‑win_amd64.whl” I suggest you follow the installation procedure described under “Directly (Windows)” in the main page. The procedure is pretty straightforward and easy to follow, you should be able to install it without much difficulty.
