TypeError：不可订购类型：str（）＆lt;int（）

有人可以建议吗？谢谢
我遇到了相同的错误，并且能够通过安装libfreetype6-dev和libpng12-dev来解决它。
sudo apt-get install libfreetype6-dev libpng12-dev
感谢@koukouviou指向上游错误报告，该报告大大加速了解决方案查找过程。
Matplotlib的GitHub跟踪器中有一个封闭的问题。Matplotlib不是问题，而是其他软件包（讨论中提到了Freetype和PNG）。
根据讨论，错误消息在主分支中更具描述性：
- 无法构建以下所需软件包： * freetype，png
