错误:LaTeX中缺少\ begin {document} [英] Error: missing \begin{document} in LaTeX

问题描述

我的LaTeX文档中有错误，运行文件时出现错误

I have error in my LaTeX document, when run my file, have a error

! LaTeX Error: Missing \begin{document}.

并且此标记\begin{document}存在于我的代码中

and this tag \begin{document} exists in my code

\documentclass[12pt‎, ‎a4paper]{article}‎
\usepackage{graphicx}  % inserting images
\usepackage[top=3cm,right=3cm,bottom=2.5cm,left=2.5cm]{geometry}                 
\usepackage[colorlinks,linkcolor=blue,citecolor=red]{hyperref} 
\usepackage{multirow}
\usepackage{subfig}
\usepackage{algorithm}
\usepackage{algorithmic}
%\usepackage[utf8]{inputenc}
%\usepackage{color, pdfcolmk}
%\usepackage{sweave}

%---------------------end list-------------------------------------

%\usepackage{geometry}\geometry{left=35mm,right=35mm,  top=30mm,bottom=30mm}


\begin{document}
\pagenumbering{gobble}
\clearpage
\thispagestyle{empty}

推荐答案

当我将此处显示的代码使用UTF-8输入编码复制到Notepad ++中时，第一行得到以下结果:

When I copy the code you have shown here into Notepad++ with UTF-8 input encoding, I get the following result for the first line:

\documentclass[12pt?, ?a4paper]{article}?

据此，我假设您有LaTeX无法识别的非UTF-8字符，因此会引发错误.尝试用替换该行

From that I assume that you have non-UTF-8 characters which aren't recognized by LaTeX and thus it throws an error. Try to replace that line by

\documentclass[12pt, a4paper]{article}

如@nowox在评论中所述，\end{document}丢失.确保文件中包含该文件.

As @nowox remarked in a comment, the \end{document} is missing. Make sure that you have that in your file.
