poetry管理安装包

基本用法

# 初始化，生成 pyproject.toml
poetry init
poetry new poetry-demo 

创建虚拟环境

poetry env use python
poetry env python3.8
poetry env use 3.8 # 激活或创建虚拟环境
poetry env system # 激活系统默认的 python


poetry env remove 3.8 # 删除环境
poetry env list # 查看所有虚拟环境

poetry env activate
poetry env deacti

use xxx根据系统环境变量PATH中 python 的版本号来创建虚拟环境，因此要确保 xxx 存在于 PATH

Windows系统下 poetry 虚拟环境安装在 \Users\username\AppData\Local\pypoetry\Cache\virtualenvs\，MacOS在 /Users/username/Library/Caches/pypoetry/virtualenvs

安装依赖

poetry install # 安装 pyproject.toml 中所有依赖，按照 poetry.lock 中的版本安装
poetry add requests
poetry lock # 将 pyproject.toml 和 poetry.lock 同步
poetry update # 根据 pyproject.toml 中的版本更新包，并重新生成 poetry.lock

poetry show # 查看所有安装的 packages
poetry show --tree # 查看所有安装的 packages 以及依赖关系

没有虚拟环境时安装包，会自动创建虚拟环境
