只要我不使用\printbibliography命令，我的文档就会编译而不会出现错误和警告。
一旦我尝试打印参考书目，我就会收到以下消息：
Undefined control sequence.<argument> \datecircaprint \mkbibdateapalongextra {labelyear}{labelmonth}{la... l.78 \end{frame}
Package biblatex Warning: Bibliography string 'retrieved' undefined at entry 'some-3' on input line 78.
Package biblatex Warning: Bibliography string 'from' undefined at entry 'some-3' on input line 78.
以及参考书目中的奇怪字符串，例如labelyearlabelmonthlabelday).：
根据：BibLaTeX（APA 样式）生成的参考书目中“检索自”的问题，我尝试通过添加以下内容来解决此问题：
\usepackage[polish]{babel}
\DeclareLanguageMapping{polish}{polish-apa}
但没有帮助。
我的MWE如下：

使用
\usepackage[english]{babel}
\DeclareLanguageMapping{english}{english-apa}
当我运行您的示例时有效，即
\documentclass[10pt, compress, xcolor={usenames, dvipsnames}]{beamer}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{appendixnumberbeamer}
\usepackage[export]{adjustbox}
\usepackage{graphicx}
\usepackage{multirow}
\usepackage{csquotes}
\usepackage{polski}
\uselanguage{polish}
\languagepath{polish}
\mode<presentation> {
\usetheme{Warsaw}
\setbeamertemplate{headline}{}
\usepackage[backend=biber,style=apa,citestyle=authoryear, natbib=true]{biblatex}
\DeclareLanguageMapping{english}{english-apa}
\DefineBibliographyStrings{polish}{andothers={i inni},and={i}} %% Mentioned strings are in polish, not english.
