我最近从 Debian stretch（旧稳定版）升级到了 Debian buster（稳定版）。除其他外，该软件包texlive-latex-extra（包含该listing软件包）已升级从2016.20170123-5到2018.20190227-2。从那时起，编译文档会在列表前添加额外的空间。
最小示例：
\documentclass{article}
\usepackage{lipsum}
\usepackage{listings}
\begin{document}
\lipsum[1]
\begin{lstlisting}[basicstyle=\ttfamily,frame=single]
this is a listing
with two lines
\end{lstlisting}
\lipsum[2]
\end{document}
使用 Debian stretch 编译，列表前没有多余的空格：
使用 Debian buster 编译，列表前有额外的空格：
我尝试设置abovesep和belowsep，但那里定义的空间只是增加了列表上方的空间。
我怎样才能删除列表前的额外空格？谢谢！
根据下面的评论，我使用beforedaleif重新编译了 Debian 稳定版（添加了额外空间）上的文档，以查看所有版本信息。 listings 包的版本为：\listfiles\documentclass2018/09/02 1.7

答案1
listings事实证明，Debian 稳定版上的软件包 ( )版本2018/09/02 1.7包含一个错误。这也在此处描述：列出之前有额外的空间（Debian stretch 与 buster）？
那里提出的解决方案对我来说不起作用（我没有让它工作\lst@AddToHook），但根据用户的建议siracusa，listings可以将包本地安装到与文档相同的目录中，如下所示：
- 从这里下载
listings.ins、listings.dtx和：lstdrvrs.dtxhttps://www.ctan.org/texarchive/macros/latex/contrib/listings - 通过运行提取文件
etex listings.ins - 通过运行照常编译文档，首选
pdflatex本地版本的包listings
谢谢您的帮助和提示！:)
