\printbibliography (biblatex) 中未定义控制序列

Question

编辑：根据建议，我添加了：

\usepackage[utf8]{inputenc}

并改变了

\bibliography{citations.bib}

进入

\addbibresrouce{citations.bib}

这解决了这个特定的问题，尽管我现在有一个输入问题，但可能与这个确切的问题没有直接关系。

我遇到了一个似乎无法理解的问题，而且我在谷歌上搜索这个问题时似乎也没有找到任何东西。我不知道，也许我只是在谷歌上搜索了错误的单词。

我正在使用带有 TexShop 的 Os X，并已定义使用 biber 运行的 BibTeX 引擎。

我有（摘录）：

\usepackage[backend=biber]{biblatex}
\bibliography{citations.bib}

\begin{document}
\section{Some section}
Some text ... \cite{someBook}

\section{References}
\printbibliography
\end{document}

首先我运行了 LaTeX 编译，然后运行了 BibTeX。（确认 biber 正在运行。日志证实了这一点，同时还出现了几个警告：

/var/folders/f6/9vk9f7jn0zx_7cngdjxv1rdr0000gn/T/10ttGvYx8U/citations.bib_9023.utf8, line 46, syntax error: found "of", expected "="

然后再次运行 LaTeX-compile 时我得到以下信息：

./report, main.tx:119 处的行包含 \printbibliography 命令。我似乎无法理解为什么会出现此错误。

如果我按下回车键忽略这个错误，报告仍然会编译并生成一个看似正确的 PDF，但一直出现这个错误还是很烦人。

Answer 1

感谢 Andrew Swann 提出以下修复建议：

添加（重要提示：这不一定与我原来的问题直接相关，但却是我设置无错误运行之前所做的更改的一部分）：

\usepackage[utf8]{inputenc}

并改变：

\bibliography{citations.bib}

进入：

\addbibresource{citations.bib}

这解决了我的问题。
