請考慮這段程式碼：
\begin{filecontents*}{\jobname.bib}
@book{ kuhn:1982,
author = "Thomas Kuhn",
title = "La struttura delle rivoluzioni scientifiche",
publisher = "Einaudi",
location = "Torino",
year = "1978",
edition = "4",
}
\end{filecontents*}
\documentclass[a4paper]{article}
\usepackage{enotez}
%\DeclareInstance{enotez-list}{plain}{paragraph}{notes-sep=0pt}
\let\footnote=\endnote
\usepackage{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
\footcite[23]{kuhn:1982}
\printendnotes
\printbibliography
\end{document}
我編譯使用：pdflatex、biber、pdflatex、pdflatex。但是，我總是收到以下警告：
LaTeX Warning: There were undefined references.
Package biblatex Warning: Please (re)run Biber on the file:
(biblatex) biblio
(biblatex) and rerun LaTeX afterwards.
即使在我看來 .pdf 文件沒有問題。如果我使用包包也是一樣endnotes。為什麼這個循環？有辦法解決或避免嗎？謝謝

在您的 MWE 中缺少相關指令：\RequirePackage{filecontents}。
如果我編譯以下內容，稍微改變一下 MWE，我就沒有錯。請在您自己的計算機上檢查這一點。如果您仍然有問題，請新增\listfiles為 MWE 的第一行並重新編譯。然後檢查已使用的軟體包和版本的清單並將其添加到您的問題中。 （我猜你的系統有點過時了...）
更改了 MWE：
\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@book{kuhn:1982,
author = "Thomas Kuhn",
title = "La struttura delle rivoluzioni scientifiche",
publisher = "Einaudi",

year = "1978",
edition = "4",
}
\end{filecontents*}
