我正在构建一个 Python PIP 包，存储在 Google Artifact Registry 上。

如下pyproject.toml：

[build-system]
requires = ["setuptools>=68.0.0,<69.0.0", "setuptools-scm>=8.0.1,<8.1.0"]
build-backend = "setuptools.build_meta"

[project]
name = "my-sdk"
version = "0.1.3"
license = {text = "Some Solution"}
readme = "README.md"
requires-python = ">=3.8,<3.11"
dependencies = [
    "google-cloud-storage>=2.6.0"
]
[project.optional-dependencies]
ci = [
    "flake8==6.0.0",
    "Flake8-pyproject==1.2.3",
    "pytest-cov==4.1.0",
    "pytest==7.2.2"
]

[tool.setuptools.packages.find]
include = ["*"]
namespaces = false

[tool.pytest]
norecursedirs = [".git", ".tox"," venv*"]
addopts = "-rsxX -q -p no:warnings"
python_files = ["*_test.py", "test_*.py"]
log_cli = true
log_cli_level = "INFO"

[tool.flake8]
max-line-length = 100
select = ["E", "W", "F", "C", "B"]
ignore = ["E203", "W503", "E731"]
per-file-ignores = ["__init__.py: F401", "test_*.py: D103"]

该包的命令序列：

python -m pip install \
            keyring==24.3.0 \
            keyrings.google-artifactregistry-auth==1.1.2 \
            build==1.0.3 \
            twine==4.0.2
python -m build
python -m twine upload \
            --repository-url https://<hidden>.pkg.dev/my-project/my-artifacts \
            dist/*

只有最后一步失败，即twine upload，错误信息如下：

Traceback (most recent call last):
  File "/miniconda/envs/pip_env/lib/python3.10/runpy.py", line 187, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/miniconda/envs/pip_env/lib/python3.10/runpy.py", line 146, in _get_module_details
    return _get_module_details(pkg_main_name, error)
  File "/miniconda/envs/pip_env/lib/python3.10/runpy.py", line 110, in _get_module_details
    __import__(pkg_name)
  File "/miniconda/envs/pip_env/lib/python3.10/site-packages/twine/__init__.py", line 43, in <module>
    __license__ = metadata["license"]
  File "/miniconda/envs/pip_env/lib/python3.10/site-packages/importlib_metadata/_adapters.py", line 54, in __getitem__
    raise KeyError(item)
KeyError: 'license'

我尝试过licensepyproject.toml 中的不同类型，但每次都出现相同的错误。还有其他人遇到过这个挑战吗？

importlib-metadata 7.x 中的某个地方添加了针对DeprecationWarning: Implicit None on return values is deprecated and will raise KeyErrors.几天前发布的 importlib-metadata v8 的弃用警告，现在引发了关键错误。尝试为 importlib-metadata<8 添加限制

[project.optional-dependencies]
ci = [
    "flake8==6.0.0",
    "Flake8-pyproject==1.2.3",
    "pytest-cov==4.1.0",
    "pytest==7.2.2",
    "importlib-metadata<8.0.0"
]

您需要管理这种依赖关系，直到在 twine 中解决它为止。Twine 对 importlib-metadata 没有上限

  • 升级到 5.x。readthedocs.io/en/stable/…

在仔细查看了这些twine问题后，我找不到任何相关的答案。不过，我在 pypi.org 上看到，5.1.0 版本因类似错误而被撤下：KeyError。因此我决定升级到5.1.1，然后twine upload解决了问题。

python -m pip install \
            keyring==24.3.0 \
            keyrings.google-artifactregistry-auth==1.1.2 \
            build==1.0.3 \
            twine==5.1.1

正如下面的消息所提到的，5.1.1 解决了发布问题importlib-metadata==8.0.0。
