Anki 上的 LATEX 无法正常显示； Ubuntu 18.10
LATEX on Anki does not display properly; Ubuntu 18.10
伙计们 - 我正在尝试显示如下基本命令（许多示例之一）：
Does the sum below converge? [latex]\begin{displaymath}\sum_{k =
1}^{\infty}\frac{1}{k}\end{displaymath}[/latex]
但是它会产生以下错误：
Does the sum below converge? Error executing dvipng. Generated file:

我已经安装了 Ubuntu 18.10 运行 Anki（版本 2.1.5 Qt 5.9.2 PyQt 5.9）和 "sudo apt install texlive-latex-extra"。
非常感谢任何帮助。
嗯，缺少 dvipng。
运行 sudo apt-get install dvipng
