无法用阿拉伯语书写：软件包 babel 错误：未找到语言定义文件 main=arabic.ldf。\ProcessOptions*

我正在使用Ubuntu系统。我使用TexStudio的编辑器使用TeX Live 2017/Debian并且编辑器的编译器配置为pdflatex。

我的主要文档是英文的。但我需要在某些行中写一些阿拉伯语文本。我使用arabtex以下最小脚本：

\PassOptionsToPackage{main=arabic}{babel}
\documentclass[a4paper,twoside]{ociamthesis}
\fancyfoot[C]{\emph{DRAFT Printed on \today}}  
\correctionstrue
\newcommand*{\bibtitle}{References}

%---------- START FOR ARABIC ----------------------------
\usepackage{arabtex}
\usepackage[utf8]{inputenc}
\usepackage[LFE,LAE]{fontenc}
%---------- END FOR ARABIC ----------------------------

\title{Suitably impressive thesis title}
\author{Your Name}
\college{Your College}
\degree{Doctor of Philosophy}
\degreedate{Michaelmas 2014}

\begin{document}

\setlength{\textbaselineskip}{22pt plus2pt}
\setlength{\frontmatterbaselineskip}{17pt plus1pt minus1pt}
\setlength{\baselineskip}{\textbaselineskip}
\setcounter{secnumdepth}{2}
\setcounter{tocdepth}{2}

\begin{romanpages}
\maketitle

\begin{acknowledgements}
    \begin{otherlanguage}{arabic}
        سلام 
    \end{otherlanguage}
\end{acknowledgements}

\begin{abstract}
    My abstract here in English.
\end{abstract}

\end{romanpages}

\end{document}

但是我在编译文档时出现以下错误：

Package babel Error: Language definition file main=arabic.ldf not found. \ProcessOptions*

Package babel Error: Unknown language `arabic'. Either you have(babel) install it or just rerun the file, respectively. \begin{otherlanguage}{arabic}

\begin{alwayssingle} on input line 37 ended by \end{abstract}. \end{abstract}

\begin{romanpages} on input line 28 ended by \end{document}. \end{document}

有人能帮我弄清楚如何在英文乳胶文档中插入一些阿拉伯语文字（例如在献词或致谢部分）吗？

答案1

babel arabic.ldf（以及arabtex包）对各种命令进行了许多更改，这些命令可能会在各个地方发生冲突（例如在 minitoc 和 microtype 的组合中）。两者都相当老旧，多年来一直没有改变，因为大多数人使用 xelatex 或 lualatex 来编写此类脚本。

如果您只需要使用阿拉伯语来完成一些工作并且想要坚持使用 pdflatex，您应该考虑避免加载 arabic.ldf 并且只手动切换字体和方向：

\documentclass{book}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[LAE,T1]{fontenc}

\TeXXeTstate=1
\begin{document}
Some arabic

\makeatletter
\bgroup\beginR\raggedleft\fontencoding{LAE}\selectfont سلام\endR\par\egroup

\end{document}

答案2

首先，您不希望主要语言是阿拉伯语，对吗？

其次，arabtex进行了几次与文档类别冲突的重新定义；将其删除。

您还需要恢复拉丁输出编码。
