This is a known bug that has been fixed (https://github.com/matplotlib/matplotlib/pull/3414) on master.
这是一个已知错误，已在 master 上修复（https://github.com/matplotlib/matplotlib/pull/3414）。
The bug is in the handling of searching for a freetypeinstallation. If you install the Linux package freetype-dev, you will avoid this bug and be able to compile matplotlib.
该错误在于搜索自由类型安装的处理。如果您安装 Linux 软件包 freetype-dev，您将避免此错误并能够编译matplotlib.
sudo apt-get install libfreetype6-dev
