UnicodeDecodeError pythontex

Question

当我尝试使用 xelatex --8bit 和 pythontex 编译以下最小示例时发生错误。

\documentclass[a4paper]{book}

\usepackage{fontspec}
\defaultfontfeatures{Ligatures=TeX}

\usepackage{pythontex}

%%%%%%%%%%%%
\begin{document}

\section{Première section}

\py{1+10}

\end{document}

执行 pythontex 后，我收到以下消息。

This is PythonTeX 0.16
Traceback (most recent call last):
  File "/Library/TeX/texbin/pythontex", line 62, in <module>
    pythontex.main()

    path += '/' + b
UnicodeDecodeError: 'ascii' codec can't decode byte 0xcc in position 47: ordinal not in range(128)

我该如何修复它？对于排版，我在 MacOS 上使用 TeXPad 和以下脚本：

#!/bin/bash
# Texpad build (.tpbuild) file to use PythonTeX within Texpad
# NB this is to demonstrate pythontex only, it would need alterations     to support bibliographies, indices, etc.

xelatex -8bit -synctex=1 "$TEXPAD_ROOTFILE"
pythontex --runall=true "$TEXPAD_ROOTFILE_NO_EXT"
bibtex "$TEXPAD_ROOTFILE_NO_EXT"
xelatex -8bit "$TEXPAD_ROOTFILE"
xelatex -8bit -synctex=1 "$TEXPAD_ROOTFILE"

或者简单地

xelatex -8bit namefile
pythontex --runall=true namefile
bibtex namefile
xelatex -8bit namefile
xelatex -8bit -synctex=1 namefile

在贝壳上。
