编译时出现问题

编译时出现问题

我正在尝试编写我的章节论文使用 texmaker。当我按 F6 时,控制台日志文件返回:

日志文件很大,我粘贴一部分:

This is pdfTeX, Version 3.14159265-2.6-1.40.15 (TeX Live 2015/dev/Debian) (preloaded format=pdflatex 2017.5.25)  26 MAY 2017 00:46

! LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

You're in trouble here.  Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.

Missing character: There is no L in font nullfont!
Missing character: There is no a in font nullfont!

感谢您的帮助。欢迎提出任何建议

编译了错误的文件intro.tex。它以文本 开头Las computadoras。查找以 开头的文件\documentclass并使用 LaTeX 编译此文件。
