关于项目管理:Windows-下多版本-Python-共享-Poetryqbit

前言

• 技术栈

  Windows 10
  Python  3.8.10
  Python  3.11.2
  pip     23.0.1
  pipx    1.2.0
  poetry  1.4.1

• Python 3.8 装置目录

  C:\Python38

• Python 3.11 装置目录

  C:\Python311

装置 poetry

• 设置将以下门路退出 path 环境变量

  C:\Python38
  C:\Python38\Scripts
  C:\Python311
  C:\Python311\Scripts
  C:\Users\qbit\.local\bin\

• 复制文件

  C:\Python38\python.exe -> C:\Python38\py38.exe 
  C:\Python311\python.exe -> C:\Python38\py311.exe 

• 设置 pip 国内镜像源

  py38 -m pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/
  py311 -m pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/

• 降级 pip

  py38 -m pip install pip --upgrade
  py311 -m pip install pip --upgrade

• 装置或降级 pipx

  py38 -m pip install pipx --upgrade
  py311 -m pip install pipx --upgrade

• 在 Python 3.11 下用 pipx 装置 Poetry

  py311 -m pipx install poetry --force -i https://mirrors.aliyun.com/pypi/simple/

• 查看装置状况

  > where poetry
  c:\Users\qbit\.local\bin\poetry.exe
  > poetry --version
  Poetry (version 1.4.1)

• 设置将虚拟环境目录放在我的项目内

  poetry config virtualenvs.in-project true

测试多版本共享

测试 Python 3.11

• 创立空目录 F:\tmp\test311，在外面创立文件 pyproject.toml，文件内容如下：

  [tool.poetry]
  name = "test"
  version = "0.1.0"
  description = ""authors = ["qbit"]
  readme = "README.md"
  
  [[tool.poetry.source]]
  name = "aliyun"
  url = "https://mirrors.aliyun.com/pypi/simple/"
  default = true
  
  [tool.poetry.dependencies]
  python = "^3.11"
  requests = "~2.28.2"
  
  [build-system]
  requires = ["poetry-core"]
  build-backend = "poetry.core.masonry.api"

• 创立虚拟环境并装置第三方库

  poetry update -vv

• 查看虚拟环境信息

  > poetry env info
  
  Virtualenv
  Python:         3.11.2
  Implementation: CPython
  Path:           F:\tmp\test\.venv
  Executable:     F:\tmp\test\.venv\Scripts\python.exe
  Valid:          True
  
  System
  Platform:   win32
  OS:         nt
  Python:     3.11.2
  Path:       C:\Python311
  Executable: C:\Python311\python.exe

  测试 Python 3.8

• 创立空目录 F:\tmp\test38，在外面创立文件 pyproject.toml，文件内容如下：

  [tool.poetry]
  name = "test"
  version = "0.1.0"
  description = ""authors = ["qbit"]
  readme = "README.md"
  
  [[tool.poetry.source]]
  name = "aliyun"
  url = "https://mirrors.aliyun.com/pypi/simple/"
  default = true
  
  [tool.poetry.dependencies]
  python = "^3.8"
  requests = "~2.28.2"
  
  [build-system]
  requires = ["poetry-core"]
  build-backend = "poetry.core.masonry.api"

• 切换 python 环境

  poetry env use C:\Python38\python.exe

• 创立虚拟环境并装置第三方库

  poetry update -vv

• 查看虚拟环境信息

  > poetry env info
  
  Virtualenv
  Python:         3.8.10
  Implementation: CPython
  Path:           F:\tmp\test38\.venv
  Executable:     F:\tmp\test38\.venv\Scripts\python.exe
  Valid:          True
  
  System
  Platform:   win32
  OS:         nt
  Python:     3.8.10
  Path:       C:\Python38
  Executable: C:\Python38\python.exe
