报错信息如下:
Traceback (most recent call last):

File "/home/admin/miniconda3/lib/python3.9/site-packages/vnpy/trader/ui/init.py", line 9, in <module>
from PyQt5 import QtGui, QtWidgets, QtCore
ImportError: libGL.so.1: cannot open shared object file: No such file or directory
ubuntu版本:18.0.4

运行apt search libGL

找下有没有这个库，没有就apt install装下再试试

python 3.9 版本高了，必须3.7
