python-poetry - 诗歌看到一个间接依赖(python 的 numpy)已经过时，但没有更新它

Question

试用 poetry 1.1.11 并在我的 pyproject.toml 的 tool.poetry.dependencies 部分中添加 pandas。 Pandas 依赖于 numpy

pandas 1.3.3 Powerful data structures for data analysis, time series, and statistics
├── numpy >=1.17.3
├── python-dateutil >=2.7.3
│   └── six >=1.5 
└── pytz >=2017.3

当我调用 poetry add pandas 时，它正确安装了 numpy 1.21.1。 Numpy 已经升级到 1.22.2 并且 poetry 认识到这一点

poetry show --outdated
numpy 1.21.1 1.21.2 NumPy is the fundamental package for array computing with Python.

但是 numpy 不会被诗歌更新。

poetry update

No dependencies to install or update

这是预期的吗？ numpy 如何/何时更新？

EDIT2:根据@finswimmer 的要求，这是 TOML 并且比第一个 EDIT TOML 更简单。这是一个来自 poetry new 的空项目。然后尝试 poetry add numpy 如下。

只是

[tool.poetry]
name = "delete_me4"
version = "0.1.0"
description = ""
authors = ["Your Name <you@example.com>"]

[tool.poetry.dependencies]
python = "^3.9"

[tool.poetry.dev-dependencies]
pytest = "^5.2"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

❯ poetry add numpy
Using version ^1.21.2 for numpy

  SolverProblemError

  The current project's Python requirement (>=3.9,<4.0) is not compatible with some of the required packages Python requirement:
    - numpy requires Python >=3.7,<3.11, so it will not be satisfied for Python >=3.11,<4.0
  
  Because numpy (1.21.2) requires Python >=3.7,<3.11
   and no versions of numpy match >1.21.2,<2.0.0, numpy is forbidden.
  So, because delete-me4 depends on numpy (^1.21.2), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For numpy, a possible solution would be to set the `python` property to ">=3.9,<3.11"

Answer 1

上面帮助文本中的建议解决了这个问题。 poetry add numpy 使用此 TOML 更改在空项目中工作。

[tool.poetry.dependencies]
python = ">=3.9,<3.11"

我不确定是什么触发了它想要 Python >= 3.11 去范围，但是嘿。一旦我尝试了重现，它就解决了我的问题。

请注意，如下进一步限制 Python 允许 scipy 从 1.6.1 移动到 1.7.1

[tool.poetry.dependencies]
python = ">=3.9,<3.10"
