![使用 tcolorbox 的不良空间因素](https://linux22.com/image/375838/%E4%BD%BF%E7%94%A8%20tcolorbox%20%E7%9A%84%E4%B8%8D%E8%89%AF%E7%A9%BA%E9%97%B4%E5%9B%A0%E7%B4%A0.png)
我正在尝试了解 tcolorbox 包的工作原理,但我从手册中复制/粘贴的一些代码有问题……老实说,我不明白哪里出了问题。你能帮帮我吗?
这是我的代码:

\section{re}
\begin{exercise}
Compute the derivative of the following function:
\begin{equation*}
f(x)=\sin((\sin x)^2)
\end{equation*}
\tcblower
The derivative is:
\begin{align*}
f
'
(x) &= \left( \sin((\sin x)^2) \right)
'
=\cos((\sin x)^2) 2\sin x \cos x.
\end{align*}
\end{exercise}
\end{document}
这会导致编译时出现错误行 106,原因如下:!错误的空间因子 (0)。 \@savsf \end{exercise} 如果我不使用以下行,错误就会消失 \tcblower

答案1
复制和粘贴时出现错误的换行符,例如在savelowerto
键的值中。
还要确保该solutions
文件夹存在。
