Bibtex 引文无法加载，显示为问号

我正在 Pycharm 中使用 TeXiFy IDEA 插件，因为它对我的工作来说很方便。

我不断浏览论坛寻找类似的错误，但找不到有效的解决方案。

.tex 文件中的相关示例：

    Stars are classified based on their temperature, put into classes denoted by the letters, known as the Current Harvard System\cite{1901AnHar..28..129C}.

    \bibliography{main}
    \bibliographystyle{plain}

我的.bib 文件：

@ARTICLE{1901AnHar..28..129C,
    author = {{Cannon}, Annie J. and {Pickering}, Edward C.},
    title = {Spectra of bright southern stars photographed with the 13-inch Boyden telescope as part of the Henry Draper Memorial},
    journal = {Annals of Harvard College Observatory},
    keywords = {STARS: SPECTRA, STARS: CATALOGS, STARS: CLASSIFICATION},
    year = {1901},
    month = {jan},
    volume = {28},
    pages = {129-P.6},
    adsurl = {https://ui.adsabs.harvard.edu/abs/1901AnHar..28..129C},
    adsnote = {Provided by the SAO/NASA Astrophysics Data System}

从上述文件可以看出，.bbl 文件是空的：

\begin{thebibliography}{}

\end{thebibliography}

我怀疑这与编译器有关，但这不是我第一次使用 TeXiFy，它以前就起作用了。

讯息

我无法打开数据库文件 main.bib

只能意味着一件事：BibTeX 无法打开文件main.bib。如果 bib 文件名拼写错误和/或文件main.bib存在但不在 BibTeX 的搜索路径中，则会发生这种情况。

对您的 bib 文件的一些评论：(a) 无需将作者姓氏括在花括号中；(b) 请将Boyden和括Henry Draper Memorial在花括号中；(c) 此行month = {jan},错误；(d) 由于您使用的是natbib引文管理包，请考虑使用plainnat而不是plain作为参考书目样式。并且，为了让 BibTeX 有机会获得正确的格式，请写month = jan,而不是month = {jan},。
