仅使用Pyproject.toml的Setuptools Python项目如何指定替代依赖源？

Got it, since you're relying solely on pyproject.toml (ditching setup.py and setup.cfg), setting up your custom Artifactory repository as a dependency source depends on which build/dependency manager you're using. Let's break down the two most common setups:

1. If you're using Poetry #

Poetry leans heavily on pyproject.toml for all config, so adding your custom repo is straightforward. Just add a [[tool.poetry.source]] section to your file:

[[tool.poetry.source]]
name = "my-artifactory"  # A unique name for your repo
url = "https://artifactory.mypypy.com/simple/"  # Make sure it ends with /simple/
default = true  # Set this if you want this repo to be the primary source (instead of PyPI)
# Or use secondary = true if you want to use it alongside PyPI

• If you set default = true, Poetry will look here first for all dependencies.
• If you only need specific packages from this repo, you can mark them when adding dependencies: poetry add my-package --source my-artifactory

2. If you're using Setuptools (with pyproject.toml) #

For setuptools, you can configure the repository directly in the tool.setuptools section. If this is your primary index, use:

[tool.setuptools]
index-url = "https://artifactory.mypypy.com/simple/"

If you need to add this as an extra index alongside PyPI, use:

[tool.setuptools]
index-url = "https://pypi.org/simple/"  # Keep PyPI as primary
extra-index-url = ["https://artifactory.mypypy.com/simple/"]

Alternatively, use the newer, more flexible index list syntax for multiple repos:

[[tool.setuptools.indexes]]
url = "https://artifactory.mypypy.com/simple/"
name = "my-artifactory"
priority = "high"  # Use "low" if you want PyPI to take precedence

3. For direct pip usage (without a dedicated manager) #

If you're just using pip to install from your pyproject.toml, add pip-specific config to point to your repo:

[[tool.pip.indexes]]
url = "https://artifactory.mypypy.com/simple/"

Or, if you need to combine it with PyPI:

[[tool.pip.indexes]]
url = "https://pypi.org/simple/"
name = "pypi"

[[tool.pip.indexes]]
url = "https://artifactory.mypypy.com/simple/"
name = "my-artifactory"

Quick Note on Authentication #

If your Artifactory repo requires credentials, you can handle this via:

• A ~/.pypirc file with your repo name and credentials
• Environment variables (check your tool's docs for exact variable names, e.g., MY_ARTIFACTORY_USERNAME and MY_ARTIFACTORY_PASSWORD)
