Python:PyNomo 示例的断开管道错误(在函数 Nomographer 中)

Question

我在Python 2.7上使用pycharm。我已经安装了PyNomo.我正在尝试从官方网站运行这个小示例。链接上提供了代码，我只是复制粘贴了它。我收到以下错误：

Aligning with tag A
Traceback (most recent call last):

    texrunner.texinput.write("n\endn")

错误位于代码的最后一行：

Nomographer(main_params)

我看过其他带有"断管错误"的问题：这里，这里和这里。但它们对我没有帮助。

任何关于如何解决的指示都将非常有帮助。

>PyNomo使用 TeX 安装来排版文本。也许这是缺失导致管道破裂。您需要能够在命令行上运行文件hello.tex内容Hello, world!bye tex hello.tex。它应该导致文件hello.dvi 。如果没有，你需要安装一个像TeXLive这样的TeX发行版。
