我正在准备使用他们的模板（QIC LaTeX2e）。我正在默认的 Overleaf 项目中进行编译，并添加了一些包以便使用我的宏：\usepackage{amsfonts, amsmath, nicefrac, hyperref, amssymb, listings, xcolor}。当呈现示例书目时

输出中的引用以“pt!”开头，Overleaf 给出了以下错误：
Package calc Error: `0' invalid at this point.
See the calc package documentation for explanation.
Type H <return> for immediate help.

l.230 \bibitem
{first}
I expected to see one of: + - * / )
! Missing number, treated as zero.
<to be read again>
\protect
l.230 \bibitem
{first}
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.)
Illegal unit of measure (pt inserted).
<to be read again>

l.230 \bibitem
{first}
Dimensions can be in units of em, ex, in, pt, pc, cm, mm, dd, cc, nd, nc, bp, or sp; but yours is a new one! I'll assume that you meant to say pt, for printer's points. To recover gracefully from this error, it's best to delete the erroneous units; e.g., type `2' to delete two letters. (See Chapter 27 of The TeXbook.)
LaTeX Error: Something's wrong--perhaps a missing \item.
There are no entries found in a list you have created. Make sure you label list entries using the \item command, and that you have not used a list inside a table.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.230 \bibitem
{first}
Try typing <return> to proceed. If that doesn't work, type X <return> to quit.
看来编译器不喜欢赋予bibitems 的名称，并且由于某种原因需要一个长度。
以下是样式文件中的代码thebibliography：
\renewenvironment{thebibliography}[1]
{\frenchspacing
\small\rm\baselineskip=11pt
\begin{list}{\arabic{enumi}.}
{\usecounter{enumi}\setlength{\parsep}{0pt}
% \setlength{\leftmargin 12.7pt}{\rightmargin 0pt}%FOR 1--9 ITEMS
\setlength{\leftmargin 17pt}{\rightmargin 0pt} %FOR 10--99 ITEMS
% \setlength{\leftmargin 22pt}{\rightmargin 0pt} %FOR 100+ABOVE ITEMS
\setlength{\itemsep}{0pt} \settowidth
{\labelwidth}{#1.}\sloppy}}{\end{list}}
解决这些错误的最干净的解决方案是什么？我真的不想放弃我的宏和相应的先决条件包。
