问题要安装pyproject.toml依赖项 我有一个由诗歌创造的旧项目。 pyproject.toml由诗歌创造是以下内容： [工具。 名称=“ dota2learning” 版本=“ 0.3.0” 描述=“ stati ...

Question

如果运行“ PIP安装。”它对我有用，但是现在，我想在没有诗歌的情况下遵循新方法来管理项目和依赖关系。然后我创建了一个新的pyproject.toml（手动）：

[project]
name = "Dota2Learning"
version = "2.0.0"
description = "Statistics and Machine Learning for your Dota2 Games."
license = "MIT"
readme = "README.md"
homepage = ""
requires-python = ">=3.10"
repository = "https://github.com/drigols/dota2learning/"
documentation = ""
include = ["CHANGELOG.md"]
authors = [
    "drigols <[email protected]>",
]
maintainers = [
    "drigols <[email protected]>",
]
keywords = [
    "dota2",
    "statistics",
    "machine Learning",
    "deep learning",
]

dependencies = [
    "requests>=2.27.1",
    "typer>=0.4.1",
    "SQLAlchemy>=1.4.39",
    "PyMySQL>=1.0.2",
    "cryptography>=37.0.4",
    "pydantic>=1.9.1",
    "rich>=12.5.1",
    "fastapi>=0.79.0",
    "uvicorn>=0.18.2",
]

[project.optional-dependencies]
# Dev dependencies.
dev = [
    "black>=22.3.0",
    "pre-commit>=2.19.0",
    "flake8>=4.0.1",
    "reorder-python-imports>=3.1.0",
    "pyupgrade>=2.34.0",
]
# Testing dependencies.
test = [
    "coverage>=6.4.1",
]
# Docs dependencies.
doc = []

[project.scripts]
dota2learning = "dota2learning.cli.main:app"

[tool.black]
line-length = 79
include = '\.pyi?$' # All Python files
exclude = '''
/(
    \.git
  | \.hg
  | \.mypy_cache
  | \.tox
  | \.venv
  | _build
  | buck-out
  | build

)/
'''

现在问题是pip命令

“ pip install。”不起作用：

pip不知道如何从pyproject.toml安装依赖项，与诗歌的方法不同，我不明白为什么。

问题解决了！ A对pyproject.toml进行了编辑：

[build-system]
# Minimum requirements for the build system to execute.
requires = ["setuptools", "wheel"]  # PEP 508 specifications.
build-backend = "setuptools.build_meta"

# Ignore flat-layout.

变性问题：

1.

Answer 1

license

部分下的

[project]

键存在问题。它的价值应该是一张桌子。参见规定 22。您显示的新文件缺少

pyproject.toml

部分。如果本节不存在，则构建前端（例如PIP）将假设该项目的后端是

[build-system]

（请参阅PEP517

和

PEP518），而不是setuptools

/

poetry

，这可能是您想要的。

3.3截至今天，诗歌与此新的poetry-core文件不兼容。诗歌尚未实施[project]的变化，因此无论如何都无法正常工作，除非项目将其构建后端从诗歌更改为另一个构建后端。
