Using textstudio, we encountered a small error

Source code:

\begin{thebibliography}{}
\bibliographystyle{aaa} % template
\bibliography{references} % references
%
% and use \bibitem to create references. Consult the Instructions
% for authors for reference list style.
%
\item{a}
% Format for Journal Reference
Author, Article title, Journal, Volume, page numbers (year)
% Format for books
%\bibitem{b}
Author, Book title, page numbers. Publisher, place (year)
% etc
\end{thebibliography}

report errors:

Something’s wrong–perhaps a missing \item. \begin{thebibliography}{1}

After checking for a long time, I didn’t find the reason, and the online method was also wrong. Later, I found that I made a low-level mistake: the template file and the bib file were misplaced.

Solution: will

\bibliographystyle{spbasic} % template
\bibliography{references} % references

Put in

\begin{thebibliography}{}

\End {the bibliography}
just ahead of this interval.
