与我的 latex 文件位于同一目录中：
\documentclass[os, article]{copernicus}
\usepackage{cite}
\begin{document}
\title{text}
\Author[1]{my}{name}
\affil[1]{University}
\runningtitle{title}
\runningauthor{my name}
\correspondence{my email)}
\received{}
\pubdiscuss{} %% only important for two-stage journals
\revised{}
\accepted{}
\published{}
\firstpage{1}
\maketitle
\begin{abstract}
I will fill in the abstract text later on..
\end{abstract}
\introduction %% \introduction[modified heading if necessary]
\upshape{ text \cite{essd-7-47-2015}}
%% REFERENCES
%% The reference list is compiled as follows:
% I don't know what to do with this!!
%\begin{thebibliography}{}
%
%\bibitem[AUTHOR(YEAR)]{LABEL}
%REFERENCE 1
%
%\bibitem[AUTHOR(YEAR)]{LABEL}
%REFERENCE 2
%
%
%\end{thebibliography}
%% authors experienced with BibTeX only have to include the following two lines:
%%
\bibliographystyle{copernicus}
\bibliography{oceanbib} % my bib file in same directory
%% LITERATURE CITATIONS
%%
%% command & example result
%% \citet{jones90}| & Jones et al. (1990)
%% \citep{jones90}| & (Jones et al., 1990)
%% \citep{jones90,jones93}| & (Jones et al., 1990, 1993)
%% \citep[p.~32]{jones90}| & (Jones et al., 1990, p.~32)
%% \citep[e.g.,][]{jones90}| & (e.g., Jones et al., 1990)

%% \citeauthor{jones90}| & Jones et al.

\end{document}
为什么我会收到如下错误：
软件包 natbib 警告：第 n 页上的引用“essd-7-47-2015”未定义输入
在 \cite 行上运行 latex typoset 时
运行 bibtex 排版时：
在 .aux 文件中未找到 \citation、\bbdata 和 \bibstyle 命令
谁能帮我！？！
提前欢呼！
答案1
copernicus我将您的文件保存在具有类的目录中，michael.tex并且还有oceanbib.bib。我做了一些更改：
- 删除了不存在的
article选项 - 固定
\Author[1]{my}{name}到\author[1]{my name} - 删除了
\usepackage{cite}与natbib（由类加载）不兼容的内容 \conclusions根据模板要求添加了一个部分。
\documentclass[os]{copernicus}
\begin{document}
\title{text}
\author[1]{my name}
\affil[1]{University}
\runningtitle{title}
\runningauthor{my name}
\correspondence{my email)}
\received{}
\pubdiscuss{} %% only important for two-stage journals
\revised{}
\accepted{}
\published{}
\firstpage{1}
\maketitle
\begin{abstract}
I will fill in the abstract text later on..
\end{abstract}
\introduction %% \introduction[modified heading if necessary]
text \cite{essd-7-47-2015}
\conclusions
zzz
\bibliographystyle{copernicus}
\bibliography{oceanbib} % my bib file in same directory
\end{document}
然后我就这么做了
pdflatex michael
bibtex michael
pdflatex michael
pdflatex michael
此后，输出符合预期：
