沿路径叠加文本

Question

<2->在 beamer 中，我无法使用诸如和 之类的覆盖规范显示第二张幻灯片上的路径上方的文本onslide<2->。该怎么办？

\documentclass{beamer}
\usepackage{tikz}

\begin{document}
\begin{frame}{}
  \begin{tikzpicture}
    % Error: giving up on this path
    \draw (0,0) to node<2-> [sloped, above = 5pt] {text} (1,1);
    % Error: giving up on this path
    \draw (0,0) to \onslide<2->{node [sloped, above = 5pt] {text}} (1,1);
  \end{tikzpicture}
\end{frame}
\end{document}

没有问题overlay-beamer-styles。

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{overlay-beamer-styles}
\begin{document}
\begin{frame}{}
  \begin{tikzpicture}
    \draw (0,0) to node [visible on=<2->,sloped, above = 5pt] {text} (1,1);
  \end{tikzpicture}
\end{frame}
\end{document}
