包辮子警告

Question

有人遇過這個警告嗎？

Package braids Warning: This package was designed using PGF2.10; you are using 3.0.1a.

我確定我\usepackage{tikz}以前有過\usepackage{braids}。辮子的實際代碼是

\begin{tikzpicture}
\braid[number of strands=4,
       style strands={5,6}{draw=none}] (braid) a_2 a_1 a_3 a_2 a_2 a_1 a_3 a_2;
\end{tikzpicture}
