RunTimeError: pdf Latex 未安装

问题描述

$ schtex drawing.sch drawing.png

当我尝试运行上面的代码时,它说我没有安装 pidflatex,即使我已经 pip 安装了 latex、tex 和 pdflatex。 我在测试另一段代码时也运行了以下几行,但没有获得任何东西:

from sympy.utilities.misc import find_executable
find_executable('latex')

它也给了我一个错误

解决方法

根据我的经验,运行这些软件包需要在您的计算机上实际安装 LaTeX 发行版(其中包含 pdflatex)。

我建议您使用 teXlive,这是最常见的一种:https://www.tug.org/texlive/

您也可以使用 MikTeX,这也是一个非常常见的发行版:https://miktex.org/
