Generated file

[project]
name = "pers-website-backend"
version = "0.1.0"
description = "personal website backend"
authors = [
    {name = "Henry Lin",email = "huarui.lin@outlook.com"}
]
readme = "README.md"
requires-python = ">=3.13"
dependencies = [
]


[build-system]
requires = ["poetry-core>=2.0.0,<3.0.0"]
build-backend = "poetry.core.masonry.api"


Do you confirm generation? (yes/no) [yes]
  • 查看初始化的 pyproject.toml 文件
[project]
name = "pers-website-backend"
version = "0.1.0"
description = "personal website backend"
authors = [
    {name = "Henry Lin",email = "huarui.lin@outlook.com"}
]
readme = "README.md"
requires-python = ">=3.13"
dependencies = [
]


[build-system]
requires = ["poetry-core>=2.0.0,<3.0.0"]
build-backend = "poetry.core.masonry.api"

第二步： 导入已有依赖

  • 创建并激活虚拟环境
 poerty install

Installing dependencies from lock file

报错参考：【Poetry - Issue - The current project could not be installed: No file/folder found for package XXX 】

  • 添加原有依赖
poetry run pip install -r requirements.txt
