我有一个问题，我已经花了大量时间。想知道您是否能帮助我，或者告诉我应该怎么做。
所以基本目标：合并2个章节，并合并2个相应的.bib文件（每个章节之后）（为了简单起见）。
我可以运行一次 Latex，然后运行 Bibtex。（仅产生警告），然后我再次运行 LATEX，它会产生错误：
未定义控制序列 \printbibliography{heading=subbibliography}?
这是我的代码：
`\documentclass[openany]{report}
%\usepackage[latin9]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{float}
\usepackage{textcomp}
\usepackage{amstext}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{caption}
\usepackage[style=chicago-notes,backend=bibtex,refsegment=chapter,defernumbers=true]{biblatex}
\addbibresource[label=chapter1]{/Volumes/ARKADY/LATEX/chapter1/paper/chapter1.bib}
\addbibresource[label=chapter2]{/Volumes/ARKADY/LATEX/chapter2/tex/chapter2.bib}
