PythonTeXで簡単な例を実行すると失敗する

2024-6-13 • tag-icon

PythonTeX の v 0.12 ベータ版を使用して、次の例をコンパイルしようとしています。

\documentclass[12pt]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{pythontex}

\begin{document}

\py{2+2}

\end{document}

ファイルを実行pdflatexすると、pythontex次のエラーが発生します。

これはベータ版のバグでしょうか、それとも私が何か間違っているのでしょうか?

答え1

PythonTeX v0.12beta は Python 2.7.3 以降では動作しますが、Python 2.7.2 以前では動作しません。これは 2.7.3 で導入された変更によるものです。最終的な 0.12 リリースが Python 2.7 のすべてのバージョンで動作するように努めます。

私はPython 2.7.2で少し実験を行い、問題の根本的な原因を突き止めました。 subprocess.Popen()問題はそれではありませんでした。むしろ、shlex.split() Unicode入力をサポートしていなかったPython 2.7.3 より前。

編集 2013/08/27:PythonTeX v0.12 は Python 2.7.3 より前のバージョンを検出し、問題を回避します。
