包辫子警告

Question

有人遇到过这个警告吗？

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

\usepackage{tikz}我之前已经确认过了\usepackage{braids}。辫子的实际代码是

\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}
