我正在尝试使用 Biber 添加 APA 样式的内联引用。不幸的是，Biber 拒绝承认文章的年份，并将所有内容渲染为 nd，例如：(Johnson, 1999) 显示为 (Johnson, nd)。我正在使用 Mendeley 创建 bib 文件，bib 文件的格式看起来不错。
这是我的 tex 代码：
\documentclass[man]{apa6}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=apa,sortcites=true,sorting=nyt,backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}
\addbibresource{ref.bib}
\usepackage{setspace}
\title{ORT}
\shorttitle{Ortho}
\author{name}
\affiliation{univ name}
\leftheader{surname}
\authornote{None}
\abstract{None}
\begin{document}
Blah blah blah \parencite{Smith1999}
\end{document}
围兜条目如下所示：
@article{Smith1999,
author = {Smith, Bob},
file = {:D$\backslash$:/Users/Bob/smith1999.pdf},
journal = {Journal},
number = {1},
pages = {47--84},
title = {{Article Name}},
volume = {14},
year = {1999}
}

答案1
字段 year 似乎从来不是 biblatex-apa 标签名声明的一部分。它一定是偶然起作用的，或者是某种副作用。这似乎可以纠正这个问题：
\documentclass{article}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=apa,backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}
\addbibresource{biblatex-examples.bib}
\usepackage{setspace}
\DeclareLabeldate{%
\field{year}
\field{pubstate}
\field{date}
\literal{nodate}
}
