我尝试使用 PythonTeX v 0.12 beta 版本编译以下示例：
\documentclass[12pt]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{pythontex}
\begin{document}
\py{2+2}
\end{document}
我运行pdflatex该文件，然后在运行pythontex该文件时出现以下错误：
C:\Users\Uwe\Documents\python\Scripts\pythontex>pythontex pythntx1

Traceback (most recent call last):

这是测试版中的错误还是我做错了什么？
编辑：前六行
以下是 的前六行pythntx1.pytxcode：
=>PYTHONTEX#py#default#default#0#i####8#
2+2
=>PYTHONTEX:SETTINGS#
version=v0.12beta
outputdir=pythontex-files-pythntx1
workingdir=pythontex-files-pythntx1
现在运行代码会带来不同的错误：

答案1
PythonTeX v0.12beta 适用于 Python 2.7.3 及更高版本，但不适用于 Python 2.7.2 及更早版本。这是由于 2.7.3 中引入了更改。我将尝试使最终的 0.12 版本适用于所有版本的 Python 2.7。
我对 Python 2.7.2 进行了一些额外的实验，并找到了问题的最终根源。 subprocess.Popen()不是问题。相反，shlex.split() 不支持 Unicode 输入Python 2.7.3 之前版本。
编辑2013/08/27：PythonTeX v0.12 可以检测 2.7.3 之前的 Python 版本并解决该问题。
