习惯路径

/share/python3venv 给不同用户都可以使用的python虚拟环境

~/downloads 下载 /tmp

~/PROJECT 放置所有项目文件

/etc/script/proxy.sh 代理配置文件【wsl】

~/v2rayA 对每个使用的应用尽量分文件放置，方便查找。

python-venv

sudo apt install python3.11-venv
python3 -m venv snow-venv
python3 venv /path/to/venv
source /path/to/venv/bin/activate
which pip
which python
sudo rm -rf snow-venv/

要不我们还是用回 virtualenv/venv 和 pip 吧

source ./venv/bin/activate

BASH脚本修改环境变量实现python虚拟环境。
