乳胶：带有标题的警告

Question

我在 Overleaf 上使用以下设置：

\documentclass[%
 aip,
 jmp,%
 amsmath,amssymb,
%preprint,%
 reprint,%
 nofootinbib,
 nobibnotes,
%author-year,%
%author-numerical,%
10pt
]{revtex4-2}

\usepackage{graphicx}% Include figure files
\usepackage{dcolumn}% Align table columns on decimal point
\usepackage{bm}% bold math
\usepackage{tabularx}

\usepackage[a4paper, total={6.5in, 9in}]{geometry}

\usepackage{microtype}
\usepackage[english]{babel}
\usepackage[utf8]{inputenx}
\usepackage{bm}
\usepackage{amsbsy}
\usepackage{fixmath}
\usepackage{commath}
\usepackage{float}
\usepackage{siunitx} % notazione \num{e-}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{xcolor}
%\usepackage{subcaption}

\usepackage{hyperref}

\usepackage{curve2e}
%\usepackage{caption}
\usepackage{subcaption}
%\usepackage{silence}
%\WarningFilter{caption}{Unsupported document class}
%\usepackage[center]{subfigure}
\usepackage{comment}
%\usepackage[mathlines]{lineno}% Enable numbering of text and display math
%\linenumbers\relax % Commence numbering lines

我收到以下警告：

Package caption Warning: Unknown document class (or package), standard defaults will be used. See the caption package documentation for explanation.

问题是我已经评论了标题包（它应该不再处于活动状态），试图用 subcaption 替换它。

有没有办法解决这个警告？

Answer 1

subcaption 自动加载caption 包。如果您也删除此软件包，警告就会消失：
