How to Migrate from venv to poetry

pipx

推荐使用pipx安装poetry，但是pipx必须绑定某个python使用，因此绑定全局的python，同时将poetry通过全局的python下的 全局pipx安装，也就是得到全局的poetry。

修改源

全局
poetry config repositories.pypi https://pypi.tuna.tsinghua.edu.cn/simple
poetry config --list
poetry config unset repositories.pypi # 恢复
仅修改当前项目
[[tool.poetry.source]]
name = "tsinghua"
url = "https://pypi.tuna.tsinghua.edu.cn/simple"
priority = "primary"

[[tool.poetry.source]]
name = "pypi"
url = "https://pypi.org/simple"
priority = "supplemental"

How

从requirements.txt安装

poetry 本身不支持，只能逐个安装;

cat requirements.txt | xargs poetry add

如何在新的路径下使用旧的环境

docs-managing environments

poetry init # 创建新环境
poetry config virtualenvs.path # 找到并进入环境所在路径
# delete 新环境
# rename 旧环境 为新环境名称

根据pyproject.yaml修改poetry.lock

poetry lock

poetry show module依据poetry.lock

$VIRTUAL_ENV环境变量可能影响使用的环境

unset VIRTUAL_ENV清除，这个貌似是每个poetry项目单独的
