如何配置 Texstudio 以使用 PythonTeX？

Question

我在这里学习了如何向 TeXstudio 添加用户命令：http://texstudio.sourceforge.net/manual/current/usermanual_en.html

具体来说，对于 PythonTeX，我添加了以下命令：

然后，我形成了如下结构和视图：

txs:///pdflatex | txs:///pythontex | txs:///pdflatex | txs:///biber | txs:///pdflatex | txs:///view-pdf-internal

我已经确认pythontex.exe系统已经知道这一点，只需在控制台中运行该命令并注意以下输出：

usage: pythontex.py [-h] [--version] [--encoding ENCODING]
                    [--error-exit-code {true,false}] [--runall [{true,false}]
                    | --rerun {never,modified,errors,warnings,always}]
                    [--hashdependencies [{true,false}]] [-j N] [-v]
                    [--interpreter INTERPRETER]
                    [--debug [<family>:<session>:<restart>] | --interactive
                    [<family>:<session>:<restart>]]
                    TEXNAME
pythontex.py: error: too few arguments
C:\texlive\2016\bin\win32\runscript.tlu:679: command failed with exit code 2:
python.exe c:\texlive\2016\texmf-dist\scripts\pythontex\pythontex.py

因此，我决定在一个简单的文档上尝试我的设置：

\documentclass[12pt,letterpaper]{article}
\usepackage{pythontex}

\begin{document}

\begin{pycode}
print(r'\begin{center}')
print(r'\textit{A message from Python!}')
print(r'\end{center}')
\end{pycode}

\end{document}

但是，当我点击构建和查看按钮时，一切都挂起了，并且日志显示以下错误（行号对应于文件pythontex.sty）：

line 284: Use of \@xs@StrSubstitute@@ doesn't match its definition. \StrSubstitute{\pytx@jobname}{"}{}
line 284: Use of \\lstinline doesn't match its definition. \StrSubstitute{\pytx@jobname}{"}{}
line 284: Undefined control sequence. \StrSubstitute{\pytx@jobname}{"}{}

line 284: Undefined control sequence. \StrSubstitute{\pytx@jobname}{"}{}
line 284: Use of \@ doesn't match its definition. \StrSubstitute{\pytx@jobname}{"}{}

发生什么问题了？
