python3 -m venv /srv/python		
		
		

设置 python 版本

		
root@debian:~# update-alternatives --install /usr/bin/python python /srv/python/bin/python 1
		
		

初始化环境

		
neo@Netkiller-Mac-mini-M4 netkiller % python3 -m venv .venv
		
		

我使用的是 fish shell

			
neo@Netkiller-Mac-mini-M4 netkiller % fish

Type help for instructions on how to use fish		
			
		

切换到 venv 环境

			
neo@Netkiller-Mac-mini-M4 ~/P/netkiller (yolo)> python3 -m venv .venv	
neo@Netkiller-Mac-mini-M4 ~/P/netkiller (yolo)> source .venv/bin/activate.fish 
(.venv) neo@Neo-Mac-mini-M4 ~/P/netkiller (yolo)>
