我想包括这个图书馆在我的文档中。单独使用它很好。但是当我包含时，我在 Ball.sty 包中收到一个错误，如下所示：
\ProvidesPackage{Ball}

}
关键行是fill/.store in=\fill,和fill=green,。出于某种原因，我得到了错误
Missing number, treated as zero.
<to be read again>
g
l.55 \newskip\LTleft \LTleft=\fill
A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)
有些后续错误是基于第一个错误而产生的。
经过几个小时的调试，我完全不知道是什么导致了这个错误。也许其他人有猜测？

您不应该将与 Ti 一致的键存储在宏中钾Z 命令\fill。在我看来，最好不要在显式宏中存储任何内容，而是使用\pgfkeysvalueof{...}。因此，您可能希望将其用于Ball.sty。
\ProvidesPackage{Ball}
\tikzset{Ball/.pic={\tikzset{/sphere/.cd,#1}
\def\skv##1{\pgfkeysvalueof{/sphere/##1}}
\pgfmathsetmacro{\r}{\skv{radius}*\skv{scale}}
\shade[ball color=\skv{fill},opacity=\skv{opacity}] (0,0,0) circle (\r);
\draw (0,0,0) circle [radius=\r] node[scale=4*\r] {\skv{logo}};
\coordinate (\skv{name}-anchor) at ( 0 , 0 , 0) ;
\coordinate (\skv{name}-east) at ( \r, 0 , 0) ;
\coordinate (\skv{name}-west) at (-\r, 0 , 0) ;
\coordinate (\skv{name}-north) at ( 0 , \r , 0) ;

正如你所见，它起作用了：
\documentclass[border=3mm,tikz]{standalone}
\usetikzlibrary{quotes}
\begin{document}
\tikzset{Ball/.pic={\tikzset{/sphere/.cd,#1}
\def\skv##1{\pgfkeysvalueof{/sphere/##1}}
\pgfmathsetmacro{\r}{\skv{radius}*\skv{scale}}
\shade[ball color=\skv{fill},opacity=\skv{opacity}] (0,0,0) circle (\r);
\draw (0,0,0) circle [radius=\r] node[scale=4*\r] {\skv{logo}};
\coordinate (\skv{name}-anchor) at ( 0 , 0 , 0) ;
\coordinate (\skv{name}-east) at ( \r, 0 , 0) ;
\coordinate (\skv{name}-west) at (-\r, 0 , 0) ;
\coordinate (\skv{name}-north) at ( 0 , \r , 0) ;
\coordinate (\skv{name}-south) at ( 0 , -\r, 0) ;
\coordinate (\skv{name}-southwest) at ( -0.70710678118 * \r , -0.70710678118 * \r, 0) ;
\coordinate (\skv{name}-northeast) at ( 0.70710678118 * \r , 0.70710678118 * \r, 0) ;
\path (\skv{name}-south) + (0,-20pt) coordinate (caption-node)
edge ["\textcolor{black}{\bfseries\skv{caption}}"'] (caption-node); %Ball caption
},
/sphere/.search also={/tikz},
/sphere/.cd,
radius/.initial=0.5,
scale/.initial=0.2,
