未定義的引用

我正在做我的第一個參考書目，現在一個小時內我遇到了錯誤。 .tex 檔：

\documentclass[francais,10pt,twosides,a4paper]{report}

\usepackage[francais,polutonikogreek]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{url}
\usepackage{textgreek}

\begin{document}
\begin{quotation}
 notre âme. \cite{ref1}
 \end{quotation}
 \end{document}

還有圍兜：

@book
{ref1,
  title = {Manuel d’Épictète}
  author = {Arrien}
  publisher = {Wikisource \url{https://fr.wikisource.org/wiki/Manuel_d>%E2%80>>%99%C3%89pict%C3%A8te_(trad._Thurot)#I._Distinction_entre_ce_qui_d.C3.A9pend_de_nous_et_ce_
 qui_ne_d.C3.A9pend_pas_de_nous}},
  note = {Traduit par Jean-François Thurot} 
  year = {1889}
}

你能幫我解決這個問題嗎？謝謝。

答案1

您的程式碼中有幾個錯誤。

  1. LaTeX 需要一個命令來根據您引用的書籍、文章等知道應該在哪裡列印參考書目。
  2. 您的 bib 檔案有一些錯誤。我在下面的 MWE 中更正了它們（請參閱新增的逗號和 field 的用法url）。
  3. 您正在使用編碼 utf-8。這就是我使用套件biblatex和程式biber來創建參考書目的原因，因為 biber 可以處理 utf-8，bibtex但不能。

MWE，編譯沒有錯誤：

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@Book{goossens,
  author    = {Goossens, Michel and Mittelbach, Frank and 
               Samarin, Alexander},
