我用
\documentclass[useAMS,usenatbib]{mnras}
\usepackage{graphicx,natbib,times,amssymb}
以及警告
/usr/share/texlive/texmf-dist/tex/latex/base/fixltx2e.sty:
Package fixltx2e Warning: fixltx2e is not required with releases after 2015
(fixltx2e) All fixes are now in the LaTeX kernel.
(fixltx2e) See the latexrelease package for details.
我该如何删除 fixltx2e？我没看到它。谢谢 R. Baer
