我正在使用TEXnicCenter 2.0.2。 编译.tex和.bibtex文件后,所有引用都在.bbl文件中以bibitem转换。我在.tex文件中使用了以下bibitem:
\bibitem{nadel1990some}
B.~Nadel, \href{https://books.google.tn/books?id=f1evpwAACAAJ}{Some
applications of the constraint satisfaction problem}, no. n°~8 in CSC (Wayne
State University. Department of Computer Science), Wayne State University,
Department of Computer Science, 1990.
\newline\urlprefix\url{https://books.google.tn/books?id=f1evpwAACAAJ}
但是我在bibitem的第一行和最后一行有这个错误:
undefined control sequence
请帮助我
