kali_linux升级python3-PyQt5后retext无法工作

retext 是编辑markdown文件的工具，最近升级了python3-PyQt5后，发现retext无法正常工作了。

1. 报错如下

apt-get install python3-pyqt5
apt install retext

root@kali:~# retext
Traceback (most recent call last):
  File "/usr/bin/retext", line 26, in <module>
    from ReText import datadirs, settings, globalSettings, app_version
  File "/usr/share/retext/ReText/__init__.py", line 24, in <module>
    from PyQt5.QtCore import QByteArray, QLocale, QSettings, QStandardPaths
RuntimeError: the sip module implements API v12.0 to v12.3 but the PyQt5.QtCore module requires API v12.4
root@kali:~# sip -V
4.19.12

2. 根据报错能看出，python3-sip的和PyQt5的版本不匹配是根本原因，幸好除了retext, 我还有
sublime , 在sublime text3 里面安装两个插件，使得sublime text3可以支持markdown.
