箭头末端类型未知

箭头末端类型未知

在先前的一个问题中箭头末端类型 [-] 未知 - 即使库已加载大家一致认为“箭头末端类型未知”的错误是由于错误的环境(smartdiagram)造成的,而且tikzpicture一切都应该没问题。但我尝试运行它tikzpicture,它仍然抱怨“箭头末端类型未知”。救命!

代码如下:

\documentclass{article}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{tikz}
\usepackage{scalefnt}

\begin{document}

}

\begin {tikzpicture} [scale=2]

系统正在抱怨该参数{1.41}\microscope以及另外 100 个错误:-))。
