现象
在编译OpenHarmony 3.1的时候，使用hb进行源码编译的时候出现以下错误（基于python3.10）：
$hb set

由以上log分析其主要原因是pip3下载的库有代码不兼容的问题，根据错误把相关不兼容库的代码纠正过来即可：
nano /home/winter/.local/lib/python3.10/site-packages/prompt_toolkit/styles/from_dict.py
"""
Tool for creating styles from a dictionary.
This is very similar to the Pygments style dictionary, with some additions:
- Support for reverse and blink.
- Support for ANSI color names. (These will map directly to the 16 terminal
colors.)
