在 pyproject.toml 中指定测试依赖项并使用 pip install -e 安装它们

Question

我有一个pyproject.toml与下面类似的 Python 项目。我用来python build生成一个用于在生产环境中安装的包。对于开发环境，我使用pip install -e .

我试图弄清楚如何确保为开发环境安装测试依赖项，而不是作为生产环境的一部分。

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

[tool.setuptools]
package-dir = {"" = "src"}
packages = [
    "package-a",
    "package-b",
]

[tool.setuptools.package-data]
"*" = [
    "path/to/*.txt"
]

[project]
name = "my-project"
version = "0.0.1"

authors = [
  { name="devnectar", email="a@b.com" },
]

description = "description goes here"
readme = "README.md"
requires-python = ">=3.10"

classifiers = [
    "Programming Language :: Python :: 3",
    "License :: OSI Approved :: MIT License",
    "Operating System :: OS Independent",
]

dependencies = [
    "dep",
    "another-dep",
    "yet-another-dep"
]

[project.optional-dependencies]
dev = [
    "tox"
]

[project.urls]
"Homepage" = "https://some_url.com"
"Bug Tracker" = "https://some_url.com"

[project.scripts]
nectarserver = "entry-point-script"

[tool.tox]
legacy_tox_ini = """
    [tox]
    min_version = 4.0
    env_list = test_env

    [testenv]
    deps = pytest
    commands = pytest -s
"""

我也尝试过test，而tests不是dev试图让它发挥作用。

我遇到两个问题：

• 当我运行时pip install -e .，tox未安装
• 该命令requires.txt生成的结果install最终有一个[dev]部分，这会导致pip install -r mypackage/mypackage.egg-info/requires.txt错误。这会导致我的构建链中出现其他问题，该链依赖于构建过程中生成的requirements.txt 文件来生成其中包含项目依赖项的 Docker 层。

tox我应该如何捕获我的开发仅依赖于pyproject.toml？

Answer 1

额外的依赖项对本地包的作用与对 PyPI 上的包的作用相同；尝试

pip install -e .[dev]
