【问题描述】：
我正在尝试将 Octave 4.2.2 与 Symbolic pkg v.2.9.0 一起使用，但我收到与 sympy 包相关的错误：
Your kit looks good for running the Symbolic package. Happy hacking!

Symbolic variables in current scope:
>> a = sym( "a" );

我深入研究代码并找到这两个参考：
https://github.com/sympy/sympy/pull/18245 https://github.com/sympy/sympy/pull/19316
但我不是程序员，因此非常感谢任何想法。
我尝试卸载 sympy-1.6 并安装 sympy-1.5，但这不起作用。
感谢您的宝贵时间。
