程序包 keyval 错误：Frametitle 未定义

程序包 keyval 错误：Frametitle 未定义

我正在尝试编译 beamer 演示模板，但是它不起作用。

代码结构如下：

\documentclass{beamer}

\usepackage{pgf,pgfpages}
\usepackage{graphicx}
\usepackage{units}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage{mathrsfs}  

\mode<presentation>
{
  \usetheme{ift}
  \setbeamercovered{transparent}
  \setbeamertemplate{items}[square]
}

\usefonttheme[onlymath]{serif}
\setbeamerfont{frametitle}{size=\LARGE,series=\bfseries}

\definecolor{uibred}{RGB}{170, 0, 0}
\definecolor{uibblue}{RGB}{0, 84, 115}
\definecolor{uibgreen}{RGB}{119, 175, 0}
%\definecolor{uibgreen}{RGB}{50, 105, 0}
\definecolor{uiborange}{RGB}{217, 89, 0}


\beamertemplatenavigationsymbolsempty


\include{macros}

%\includeonlyframes{current}

\defbeamertemplate{enumerate item}{mycircle}
{
  %\usebeamerfont*{item projected}%
  %\usebeamercolor[bg]{item projected}%
  \begin{pgfpicture}{0ex}{0ex}{1.5ex}{0ex}
    %\pgfcircle[fill]{\pgfpoint{0pt}{.75ex}}{1.25ex}
    \pgfbox[center,base]{\color{uibblue}\insertenumlabel.}
  \end{pgfpicture}%
}
[action]
{\setbeamerfont{item projected}{size=\scriptsize}}
\setbeamertemplate{enumerate item}[mycircle]

\begin{document}


\end{document}

我总是收到以下消息：

!Package keyval 错误：frametitle 未定义。请参阅 keyval 包文档以了解解释。

输入 H 立即获得帮助。\setbeamersize{frametitle=\huge}

我尝试了所有方法，但似乎没有任何效果。有人能帮助我吗？

谢谢。

为了便于将来参考，可以通过将选项传递unknownkeysallowed给 beamer 来忽略这些 keyval 错误

    \documentclass[unknownkeysallowed]{beamer}

如图所示Keyval 未定义错误。
