biblatex 出现未定义的控制序列错误

biblatex 出现未定义的控制序列错误

在文档末尾使用 \printbibliography 时，biblatex 不断出现“未定义控制序列”错误。这些错误与某些参考文献标题中的特殊字符有关，例如 \textgreek。

我已经寻找过解决方案，但不幸的是，到目前为止我找到的任何方法都没有奏效。

我正在使用 TeXStudio 2.12.6，MiKTeX 中的所有软件包都已更新到最新版本。

我的非常简单、最小的示例文档是：

\documentclass[11pt,a4paper]{article}

\usepackage{fullpage}
\usepackage{setspace}
\usepackage{parskip}
\usepackage{titlesec}
\usepackage{xcolor}
\usepackage{lineno}
\PassOptionsToPackage{hyphens}{url}
\usepackage[colorlinks = true,
        linkcolor = blue,
        urlcolor  = blue,
        citecolor = blue,
        anchorcolor = blue]{hyperref}
\usepackage{etoolbox}
\AtBeginDocument{\DeclareGraphicsExtensions{.pdf,.PDF,.eps,.EPS,.png,.PNG,.tif,.TIF,.jpg,.JPG,.jpeg,.JPEG}}
\usepackage{authblk}
\usepackage[space]{grffile}
\usepackage{latexsym}
\usepackage{textcomp}
\usepackage{longtable}
\usepackage{tabulary}
\usepackage{booktabs,array,multirow}
\usepackage{amsfonts,amsmath,amssymb}
\usepackage[english]{babel}
\usepackage{csquotes}
\usepackage[section]{placeins}
\usepackage{amsmath}
\usepackage{textgreek}
\usepackage{siunitx}
\usepackage{float}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{rotating}
\usepackage[backend=biber,bibstyle=numeric,citestyle=numeric-comp,sorting=none]{biblatex}
\addbibresource{reference.bib}

\begin{document}

This reference \cite{Evans.2000} will cause an error.

\printbibliography[title={References},heading=bibnumbered]

\end{document}

reference.bib 文件仅包含这一个参考：

@Article{Evans.2000,
  author     = {Evans, M.},
  title      = {Predicting times to low strain for a 1CrMoV rotor steel using a 6-\textgreek{j} projection technique},
  journal    = {Journal of Materials Science},
  year       = {2000},
  volume     = {35},
  number     = {12},
  pages      = {2937--2948},
  issn       = {00222461},
  doi        = {10.1023/A:1004770525118},
  pagination = {page},
}

错误源于标题中的 \textgreek{j}：

! Undefined control sequence.
<argument> ... for a 1CrMoV rotor steel using a 6-\textgreek 
                                              {j} projection technique
l.42 ...aphy[title={References},heading=bibnumbered]

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

提前谢谢了！

\textgreek{j}需求greek-babel；（最小化的）示例是

\begin{filecontents*}{\jobname.bib}
@Article{Evans.2000,
  author     = {Evans, M.},
  title      = {Predicting times to low strain for a 1CrMoV rotor 
                steel using a 6-\textgreek{j} projection technique},
  journal    = {Journal of Materials Science},
  year       = {2000},
  volume     = {35},
  number     = {12},
  pages      = {2937--2948},
  issn       = {00222461},
  doi        = {10.1023/A:1004770525118},
  pagination = {page},
}
\end{filecontents*}

\documentclass[11pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}

\usepackage{csquotes}
\usepackage[
  backend=biber,
  bibstyle=numeric,
  citestyle=numeric-comp,
  sorting=none
]{biblatex}
\addbibresource{\jobname.bib}

\begin{document}

This reference \cite{Evans.2000} will cause an error.

\printbibliography[title={References},heading=bibnumbered]

\end{document}

在此处输入图片描述

或者，你可以使用textgreek一些强制转换，但编辑条目以便拥有

  title      = {Predicting times to low strain for a 1CrMoV rotor 
                steel using a 6-\texttheta\ projection technique},

以下是未经此类编辑的示例。

\begin{filecontents*}{\jobname.bib}
@Article{Evans.2000,
  author     = {Evans, M.},
  title      = {Predicting times to low strain for a 1CrMoV rotor 
                steel using a 6-\textgreek{j} projection technique},
  journal    = {Journal of Materials Science},
  year       = {2000},
  volume     = {35},
  number     = {12},
  pages      = {2937--2948},
  issn       = {00222461},
  doi        = {10.1023/A:1004770525118},
  pagination = {page},
}
\end{filecontents*}

\documentclass[11pt,a4paper]{article}

\usepackage{textgreek}

\usepackage{csquotes}
\usepackage[
  backend=biber,
  bibstyle=numeric,
  citestyle=numeric-comp,
  sorting=none
]{biblatex}

\addbibresource{\jobname.bib}

\newcommand{\textgreek}[1]{\csname sulzergreek#1\endcsname}
\newcommand{\sulzergreekj}{\texttheta}
% add all other needed letters

\begin{document}

This reference \cite{Evans.2000} will cause an error.

\printbibliography[title={References},heading=bibnumbered]

\end{document}

笔记

该filecontents*环境仅用于使示例自成一体。

在您的长篇序言中，有一些事情需要修复。

  • 删除：当 LaTeX 缺少 TIFF 支持时，\DeclareGraphicsExtensions定义诸如 之类的扩展是没有意义的.TIF

  • hyperref应该最后加载

  • latexsym是无用的，当你有amssymb。
