Python 安装旧版本的 matplotlib 导致 freetype 和 png 错误

Question

I am attempting to install the following package: https://pypi.org/project/autocluster/

However, it looks like it requires the use of matplotlib==3.0.3, as when I try to install it i get the following error:

I already have newer versions of matplotlib installed and I also tried installing older versions, but its heart is set on building new package with 3.0.3. How can either install this version correctly or bypass the issue?

pip3 install matplotlib==3.0.3 -U

Answer 1

matplotlib 3.0.3 provides wheels for Python 3.5-3.7 but not for 3.8 so pip is trying to build from sources and failed.

Use Python 3.7. Or install dependencies and build from sources .
