解决方案

  1. 90% 成功率 
    sudo apt-get install -y fonts-liberation
rm -rf ~/.cache/matplotlib
python -c "import matplotlib.font_manager as fm; fm._load_fontmanager(try_read_cache=False)"
  2. 95% 成功率 
    import matplotlib.pyplot as plt
plt.rcParams['font.family'] = 'DejaVu Sans'  # shipped with matplotlib

无效尝试

常见但无效的做法:

  1. 93% 失败

    The font file is genuinely absent; naming it does not create it.

  2. 88% 失败

    Upgrading matplotlib does not install OS-level font packages.
