Latex IPython nbconvert引文问题

我试着在IPython中引用引文。我有一些问题

我的笔记本有一个降价单元

<cite data-cite="debreu_theory_1959">(Debreu, 1959)</cite>

我的参考书目有一节

@book{debreu_theory_1959,
  address = {New Haven, {CT}},
  title = {Theory of value: An axiomatic analysis of economic equilibrium},
  shorttitle = {Theory of value},
  url = {http://books.google.com/books?hl=en\&lr=\&id=QkX10epC46cC\&oi=fnd\&pg=PA1\&dq=debreau+theory+of+value\&ots=9DNz2653qg\&sig=fKS1CYQ6ZFmXIUmOgDq3DRLPEmQ},
  timestamp = {2014-04-17 14:32:20},
  number = {17},
  urldate = {2014-04-17},
  publisher = {Yale University Press},
  author = {Debreu, Gerard},
  year = {1959},
  file = {Snapshot:/home/haldane/.mozilla/firefox/8qzu92vh.default/zotero/storage/CIEI6RPS/books.html:text/html}
}

我的命令行调用是

ipython3 nbconvert --to pdf bibliography.ipynb --template bibliography

pdf已创建，但它包含的内容是

[?]

是的，书目.ipynb、书目.tplx和书目.bib都在同一个文件夹中
