不知道从哪里开始。当我使用较大的前导时，我可以在 tikz 中绘制一些直线，但随后它会停止绘制且不显示错误。第一个例子也是https://tikz.dev/tutorial使用控件根本不起作用。
\draw (0,0) .. controls (1,1) and (2,1) .. (2,0);
它回应：
See the tikz package documentation for explanation.
Type H <return> for immediate help.
...
l.43 \draw
(0,0) .. controls (1,1) and (2,1) .. (2,0);
然后我想我最好从更少的包开始，尽可能简单，所以我选择了教程中的第一个示例
\documentclass{article} % say
\usepackage{tikz}
\begin{document}
We are working on
\begin{tikzpicture}
\draw (-1.5,0) -- (1.5,0);
\draw (0,-1.5) -- (0,1.5);
\end{tikzpicture}.
\end{document}```
But it complains
```! LaTeX Error: Missing \begin{document}.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.2 \documentclass{article}�
��% say
回到我的第一个包含大约 20 个包的文档，我仍然可以画几条直线，但它拒绝进一步绘图并且没有给出任何错误！？！？
我已清理所有临时文件 .aux、.out 等。重新运行所有内容，但仍未画出最后一行。
\draw [thick] (1,3.5) -- (1,1.5);
下面是我的第一份文档，其中包含几个包，虽然它没有画出我的最后一条直线，而且肯定不是带有“控件”的那个，但它至少可以绘制一些东西
