LaTeX 额外 } 问题

Question

您给出的错误信息Argument of \hyper@anchorstart has an extra }让我猜测，您在一个特殊的 bib 文件条目上遇到了问题，因为您给出的代码和 bib 文件在我当前的 MikTeX 2.9 系统上编译时没有任何错误或警告。

您谈到了“错误”。那么您遇到了更多错误吗？是给定的 MWE 错误还是您的代码错误？首先，我们必须确保我们讨论的是相同的代码。

因此，请将以下 MWE 复制到您的计算机中并进行编译，运行 biber 并编译两次。结果是？（对我来说：没有错误，除了之外没有警告filecontents，这没问题）。我添加了包babel并使用包filecontents将 bib 文件包含到这个 MWE 中。

梅威瑟：

\listfiles
\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@online{arduinounorev3,
  author  = {Arduino},
  title   = {Arduino uno},
  year    = {2014},
  url     = {http://arduino.cc/en/Main/arduinoBoardUno},
  urldate = {2014-12-01},
}
\end{filecontents*}


\documentclass[12pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
%\usepackage{amsmath}
%\usepackage{amsfonts}
%\usepackage{amssymb}

\usepackage[autostyle]{csquotes}
\usepackage[
  backend=biber,
  hyperref=true,
  style=numeric
]{biblatex}
\addbibresource{\jobname.bib}

\usepackage{hyperref}
\hypersetup{colorlinks=true}


\begin{document}
Content \cite{arduinounorev3}
\nocite{*}
\newpage
\printbibliography
\end{document}

在您的系统上，此 MWE 也应该可以顺利编译。如果没有，则您的安装存在问题。如果是，我猜您的 bib 文件中还有更多条目？那么其中一个条目高于给定的导致问题。逐个添加到 MWEs bib 文件中并再次编译。请检查 biber 运行的日志。文件中有错误消息blg？是吗？更正它们。没有。那么我们需要更多信息...
