Python Poetry 的默认测试对我不起作用

Question

我想尝试诗歌，但最初的 setup/test 不适合我，所以我有点困惑。我相信它应该 'just work'，所以我想我错过了一些简单的步骤？

我在 macOS 上：12.3 (21E230) 我安装了最新版本：

$ poetry --version
Poetry version 1.1.13

现在我只想要一个纯香草设置，并验证基础工作：

$ poetry new poetry_demo --src
Created package poetry_demo in poetry_demo
$ cd poetry_demo/
$ poetry install
Creating virtualenv poetry-demo in /Users/barryredmond/dev/git/poetry_demo/.venv

  • Installing pytest (5.4.3)

Installing the current project: poetry_demo (0.1.0)

$ poetry check
All set!

我认为这应该让我设置好？让运行内置测试：

$ poetry run pytest

并且只是为了验证设置是否适合任何查看此内容的人：

.

$ cat tests/test_poetry_demo.py
from poetry_demo import __version__


def test_version():
    assert __version__ == '0.1.0'

.

$ cat src/poetry_demo/__init__.py
__version__ = '0.1.0'

我也试过没有 --src 但还是一样。

poetry 在使用 poetry new 时包含的 pytest 版本已过时，不适用于 python3.10。您必须将 pytest 更新为 poetry add --dev pytest@latest。

从poetry 1.2开始，poetry在通过poetry new初始化项目时不再定义任何默认依赖。
