+## 1. 使用python虚拟环境
+### Linux下创建与使用
+```shell
+cd $project_root_dir
+python3 -m venv ./venv
+. venv/bin/activate  # 激活/切换 python环境。同步的，会修改import sys; sys.prefix等变量值
+
+pip install -r requirements.txt  # （不要使用sudo pip,它会使用非虚拟环境）安装在$dir/venv/lib/python3.7/site-packages/
+
+deactivate  # 退出 python虚拟环境
+rm -rf $project_root_dir/venv/  # 删除虚拟环境, 直接删除文件夹即可
+```
+### Windows下
+> 建议使用pycharm
+
+## 2. 项目依赖管理
+- 使用前先查看pip的版本, 区分属于python2或python3：`pip --version`
+- 记录package依赖：`pip freeze > requirements.txt`
+- 安装package依赖：`pip install -r requirements.txt`
