首先我要说的是，我完全没有编码和编程的天赋。
我使用 MikTeX（我相信是最新版本）和 WinEdt 作为界面。我想使用 flashcard 包，这样我就可以生成一些可以打印出来的抽认卡。Anki 抽认卡软件无法帮我完成这个任务（以防有人建议这样做）。
无论如何，我已经安装了 flashcard 包；它在我的包管理器中。但是，我无法让它编译我需要的 pdf。这是我尝试编译的代码示例，它直接取自文档：
\documentclass[avery5388,grid,frame]{flashcards}
\cardfrontstyle[\large\slshape]{headings}
\cardbackstyle{empty}
\begin{document}
\cardfrontfoot{Functional Analysis}
\begin{flashcard}[Definition]{Norm on a Linear Space \\ Normed Space}
A real-valued function $||x||$ defined on a linear space $X$, where
$x \in X$, is said to be a \emph{norm on} $X$ if
\smallskip
\begin{description}
\item [Positivity] $||x|| \geq 0$,
\item [Triangle Inequality] $||x+y|| \leq ||x|| + ||y||$,
\item [Homogeneity] $||\alpha x|| = |\alpha| \: ||x||$,
$\alpha$ an arbitrary scalar,
\item [Positive Definiteness] $||x|| = 0$ if and only if $x=0$,
\end{description}
\smallskip
where $x$ and $y$ are arbitrary points in $X$.
\medskip
A linear/vector space with a norm is called a \emph{normed space}.
\end{flashcard}
\begin{flashcard}[Definition]{Inner Product}
Let $X$ be a complex linear space. An \emph{inner product} on $X$ is
a mapping that associates to each pair of vectors $x$, $y$ a scalar,
denoted $(x,y)$, that satisfies the following properties:
\medskip
\begin{description}
\item [Additivity] $(x+y,z) = (x,z) + (y,z)$,
\item [Homogeneity] $(\alpha \: x, y) = \alpha (x,y)$,
\item [Symmetry] $(x,y) = \overline{(y,x)}$,
\item [Positive Definiteness] $(x,x) > 0$, when $x\neq0$.
\end{description}
\end{flashcard}
\begin{flashcard}[Definition]{Linear Transformation/Operator}
A transformation $L$ of (operator on) a linear space $X$ into a linear
space $Y$, where $X$ and $Y$ have the same scalar field, is said to be
a \emph{linear transformation (operator)} if
\medskip
\begin{enumerate}
\item $L(\alpha x) = \alpha L(x), \forall x\in X$ and $\forall$
scalars $\alpha$, and
\item $L(x_1 + x_2) = L(x_1) + L(x_2)$ for all $x_1,x_2 \in X$.
\end{enumerate}
\end{flashcard}
\end{document}
这是它产生的错误：

我也尝试了一些其他非常简单的示例，但什么也没发生。有人能帮忙吗？提前谢谢！
编辑：我尝试了一个更简单的例子，如下所示：
\documentclass[avery5371]{flashcards}
\begin{document}
\begin{flashcard}{Start}
To finish
\end{flashcard}
\end{document}
并产生了这个错误：

我认为我没有正确安装该软件包。有人知道吗？
答案1
当我尝试编译它时，它对我来说运行完美，这更加证实了你的猜测，即你的安装无法正常工作。
我不完全确定安装在哪里中断了，但如果您将此文件保存为avery5371.cfg与 .tex 文件位于同一文件夹中，您可能会成功：

或者，尝试从文档类选项中删除 [avery5371.cfg]，看看是否可以找到该包。
