lualatex 编译器提示未定义文档命令 Cote,因此无法绘制尺寸。有什么想法吗?
答案1
这很好用:
\documentclass{article}
\usepackage{tikz}
\usepackage{xparse}
\usetikzlibrary{calc}
\usepackage{ifluatex}
\ifluatex
% LuaTeX does not provide all primitives of pdfTeX.
% Many of the missing are implemented by package pdftexcmds
% via Lua code.
% Thus the following example makes \pdfstrcmp and
% \pdffilemoddate available for LuaTeX:
\usepackage{pdftexcmds}
\makeatletter
\let\pdfstrcmp\pdf@strcmp
\let\pdffilemoddate\pdf@filemoddate
