这是我的references.bib文件：
@article{fakeref,
title = {Fast-swimming sperm causes hurricanes in Africa},
volume = {7},
issn = {1234-5678},
shorttitle = {Sperm and hurricanes},
doi = {12.3456/j.ffs.2050.01.001},
abstract = {Our results suggest that fast-swimming sperm from human males are the main cause of hurricanes on the west coast of Africa.},
language = {eng},
number = {2},
journal = {Journal of Sperm and Climate Change},
author = {Eggnowitz, Eggina and Spermirowski, Sperminald},
month = apr,
year = {2050},
keywords = {Sperm,Hurricanes,Tornados,Eggs,Africa,Climate change,Global warming},
pages = {77--100}
}
这是我的 MWE（mwe.tex）：
\documentclass[twocolumn,twoside,11pt]{article}
\usepackage{natbib} %Bibliography.
\setcitestyle{number} %Cite as numbers or author-year.
\bibliographystyle{vancouver} %Reference style.
\begin{document} %Everything that's written should come next.
\title{\vspace{-1.0cm}\textbf{\Large{This is a title}}} %Title
Random text here \citep{fakeref}.
\bibliography{references}
\end{document}
当我运行以下命令时：
$ pdflatex mwe.tex
我得到以下终端输出：
$ pdflatex mwe.tex

我尝试了很多方法，但似乎都不起作用。每当我将其包含\bibliography{references}在代码中时，它都不会编译，并且我会收到相同的错误消息。有人知道哪里出了问题吗？
答案1
您的代码中的问题是您的 bib 文件名称中隐藏了字母reference.bib。请参阅以下 MWE（使用您的 bib 文件reference.bib，确保文件名中也没有隐藏字母！）：
\documentclass[twocolumn,twoside,11pt]{article}
\usepackage{natbib} %Bibliography.
\setcitestyle{numbers} %Cite as numbers or author-year.
\bibliographystyle{vancouver} %Reference style.
\begin{document} %Everything that's written should come next.
\title{\vspace{-1.0cm}\textbf{\Large{This is a title}}} %Title
Random text here \citep{fakeref}.
%\bibliography{references} % <========================================
\bibliography{references} % <===========================================
\end{document}
在带有命令的注释行中，\bibliography您可以找到隐藏的字母。在我的编辑器中，我可以看到隐藏的字母，如下所示：
编译代码（并使用numbers）\setcitestyle我得到以下结果：
答案2
你应该使用
\setcitestyle{numbers}
代替
\setcitestyle{number}
编辑：
文档中的第 2.9 节natbib说，引用模式是numbers，如参考表中所述。
