问题描述：

我在Python 2.7上使用pycharm。我已安装PyNomo。我试图运行这个small example from the official site。代码在链接上可用，我只是简单地复制粘贴它。我收到以下错误：Python：破管错误PyNomo示例（函数Nomographer）

的错误是在代码的最后一行：

Nomographer(main_params)

我已经看过了“断管错误”其他问题：here，here，并here 。但是他们没有一个对我有帮助。

任何迹象表明如何解决将是非常有益的。

PyNomo使用TeX安装来排版文本。也许这是缺少导致管道破损。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，你需要安装一个像TeXLive这样的TeX发行版。 – wobsta

工作正常！你可以把它放在答案中，所以我可以将其标记为正确的？谢谢！ –
