如何在 macOS 中安装 ucas 包

Question

今天当我编译 beamer 项目时，显示错误：

File `ucas.sty' not found. ^^M

然后我尝试在 macOS 12.4 中像这样安装 ucas 包，显示错误：

➜  ~ sudo tlmgr install ucas
tlmgr: package repository https://mirrors.sjtug.sjtu.edu.cn/ctan/systems/texlive/tlnet (not verified: gpg unavailable)
tlmgr install: package ucas not present in repository.
tlmgr: action install returned an error; continuing.
tlmgr: An error has occurred. See above messages. Exiting.

我该怎么做才能解决这个问题？这是 beamer 文件内容：

\documentclass{beamer}
\usepackage{ctex,hyperref}
\usepackage[T1]{fontenc}

% other packages
\usepackage{latexsym,amsmath,xcolor,multicol,booktabs,calligra}
\usepackage{graphicx,pstricks,listings,stackengine}

% packages and settings for bibtex
\usepackage[backend=bibtex,sorting=none]{biblatex}
\addbibresource{ref.bib}
\setbeamerfont{footnote}{size=\tiny}   % footnote for bibtex
\setbeamertemplate{bibliography item}[text]   % reference list for bibtex
\defbibheading{reference}{\section*{参考文献}}   % heading for bibtex
