根因分析

使用LaTeX文本渲染(usetex=True)时，LaTeX安装不完整或缺少所需字体。

English

Using LaTeX text rendering (usetex=True) without a complete LaTeX installation or missing required fonts.

generic

解决方案

  1. 90% 成功率 Install a full LaTeX distribution (e.g., TeX Live or MiKTeX) 
    sudo apt-get install texlive-latex-base texlive-fonts-recommended
  2. 95% 成功率 Disable usetex and use Matplotlib's built-in math rendering 
    plt.rcParams['text.usetex'] = False

无效尝试

常见但无效的做法:

  1. Installing only matplotlib with pip 95% 失败

    LaTeX is a separate system; pip cannot install it.

  2. Setting usetex=False but still getting error 80% 失败

    If usetex is False, this error should not occur; the setting might not have been reset.
