我的序言
\documentclass[12pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage[english,greek]{babel}
%\usepackage[square, numbers, comma, sort&compress]{natbib} % Use the "Natbib" style for the references in the Bibliography
\usepackage{verbatim} % Needed for the "comment" environment to make LaTeX comments
\usepackage{biblatex}
\usepackage{amsmath,amsfonts,amssymb,amscd,mathrsfs,enumerate}
\usepackage{amsthm}
\usepackage{tikz}
\usetikzlibrary{matrix}
\usepackage[all]{xy}
\usepackage{relsize}
\usepackage{pifont}
\usepackage{mathtools}
\usepackage[all]{xy}
\usepackage{relsize}
%\usepackage{fourier}
\usepackage{esvect}
\usepackage{csquotes}
\usepackage{substitutefont}
\usepackage{graphicx}
\substitutefont{LGR}{\rmdefault}{artemisia}
\usepackage{pgf,tikz}
\usepackage{mathrsfs}
\usepackage{adjustbox}
\usepackage[capposition=top]{floatrow}
\renewcommand{\qedsymbol}{\textcolor{black}{$\blacksquare$}}
\allowdisplaybreaks
\usepackage{thmtools}
\useshorthands{;}
\defineshorthand{;}{?}
\usepackage{biblatex}
\addbibresource{bibl.bib}
然后在\end{document}我写之前
\nocite{*}
\printbibliography
但什么都没有出现（没有出现参考书目）并且我收到一个错误“输入行 616 上的参考书目为空”。
有什么帮助吗？
也许这有帮助

我有同样的问题（通过 Overleaf）。作为背景，我将我的参考书目从 natbib 迁移到 biblatex，参考项目超过 300 个。据我了解，Overleaf 中的 biblatex 默认使用 biber？
然后我尝试使用 bibtex 作为其后端
\usepackage[backend=bibtex]{biblatex}，奇迹般地它就起作用了！
希望这可以帮助。
