Python：PyNomo 示例的管道损坏错误（在 Nomographer 函数中）

Question

我在 Python 2.7 上使用 pycharm。我已经安装了 PyNomo. I am trying to run this small example from the official site。代码在 link 上可用，我只是简单地复制粘贴了它。我收到以下错误：

Aligning with tag A

Process finished with exit code 1

错误在代码的最后一行：

Nomographer(main_params)

我用 "broken pipe error" 查看了其他问题：here,here, and here。但是 none 对我有帮助。

任何关于如何解决的指示都会非常有帮助。

PyNomo 使用 TeX 安装来排版文本。也许这会导致管道破裂。您需要能够在命令行 tex hello.tex 上运行具有内容 Hello, world!\bye 的文件 hello.tex。它应该生成一个文件 hello.dvi。如果没有，你需要安装像 TeXLive 这样的 TeX 发行版。
