Traceback (most recent call last):

ModuleNotFoundError: No module named 'vnpy'

你确定安装好了vnpy吗？试试pip list看看里面有没有

PS C:\Users\FAN> pip list
Package Version

deap 1.3.3
pip 22.2.2
plotly 5.10.0
pyzmq 25.0.0b1
setuptools 63.2.0
vnpy 3.3.0

这是返回结果，你看下，谢谢

是否有多个python环境

没有，刚装的python 3.10.8

看上去vnpy没安装成功，建议还是一键安装吧。如果非要手动安装可以把现在这个python卸载掉然后参考项目文档重新手动安装https://www.vnpy.com/docs/cn/windows_install.html#id7
