读取文件 tex.aux 时未找到数据库文件

Question

我正在尝试使用 BibTeX 来包含参考文献，当我编译时test.tex，一切顺利，但是当我在 WinEdt 7.0 中单击 Bibtex 时，它说

“读取文件 test.aux 时未找到数据库文件”。

该.bib文件与 位于同一文件夹中test.tex。

\documentclass{book}
\usepackage{natbib}
\begin{document}
Test citation: \citep{Jag08}
\bibliographystyle{plainnat}
\bibliography{article}
\end{document}

我用的是Windows 10，然后修改名称为article.bib。

以下是我的 的内容.bib。路径是C:\Users\wisp\Documents\temp。

 @article{Jag08,
       author = {{de Jager}, O.~C. and {Djannati-Ata{\"i}}, A.},
        title = "{Implications of H.E.S.S. observations of pulsar wind nebulae}",
      journal = {ArXiv e-prints},
    archivePrefix = "arXiv",
       eprint = {0803.0116},
     keywords = {Astrophysics},
         year = 2008,
        month = mar,
       adsurl = {http://adsabs.harvard.edu/abs/2008arXiv0803.0116D},
      adsnote = {Provided by the SAO/NASA Astrophysics Data System}
    }

我运行pdflatex test.tex，test.aux的内容是

\relax 
\citation{Jag08}
\bibstyle{plainnat}
\bibdata{article}

以下是test.blg的内容（使用winedt）

This is BibTeX, Version 0.99dThe top-level auxiliary file: test.aux
The style file: plainnat.bst
I couldn't open database file article.bib
---line 4 of file test.aux
 : \bibdata{article
 :                 }
I'm skipping whatever remains of this command
I found no database files---while reading file test.aux
Warning--I didn't find a database entry for "Jag08"
