【问题描述】：

我在Python 2.7 上使用pycharm。我已经安装了PyNomo。我正在尝试运行此small example from the official site。代码在链接上可用，我只是复制粘贴它。我收到以下错误：

Aligning with tag A

错误在代码的最后一行：

Nomographer(main_params)

我查看了其他有关“管道损坏错误”的问题：here、here 和 here。但它们都对我没有帮助。

任何关于如何解决的指示都会非常有帮助。

【问题讨论】：

PyNomo 使用 TeX 安装来排版文本。也许这是丢失导致管道破裂。您需要能够在命令行tex hello.tex 上运行内容为Hello, world!\bye 的文件hello.tex。它应该产生一个文件hello.dvi。如果没有，你需要安装一个 TeX 发行版，比如 TeXLive。

成功了！你能把它放在答案中，以便我将其标记为正确吗？谢谢！
