尝试执行@DavidCarlisle代码我仍然有错误
!缺失数字,视为零。\ l.21 ...{5cm}{4}{10pt}{2cm}{1}{5cm}{8cm}\ \lipsum[ 1] 这里应该有一个数字;我插入了“0”。(如果您不明白我为什么需要看到一个数字,请在 TeXbook 索引中查找“奇怪的错误”。)
!\ifnum 中缺少插入 =。\ l.21 ...{5cm}{4}{10pt}{2cm}{1}{5cm}{8cm}\ \lipsum[ 1] 我原本以为会看到“<”、“=”或“>”。但并没有看到。
\documentclass{article}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum

\parskip\bigskipamount

请注意我有texlive 2016
任何建议。
