Python Poetry 的默认测试对我不起作用

Question

我想尝试诗歌，但最初的设置/测试对我不起作用，所以我有点困惑。我相信它应该“正常工作”，所以我想我错过了一些简单的步骤？

\n

我使用的是 macOS：12.3 (21E230)\n我安装了最新版本：

\n

$ poetry --version\nPoetry version 1.1.13\n

\n

现在我只想要一个纯粹的香草设置，并验证基础知识是否有效：

\n

$ poetry new poetry_demo --src\nCreated package poetry_demo in poetry_demo\n$ cd poetry_demo/\n$ poetry install\nCreating virtualenv poetry-demo in /Users/barryredmond/dev/git/poetry_demo/.venv\nUpdating dependencies\nResolving dependencies... (0.1s)\n\nWriting lock file\n\nPackage operations: 8 installs, 0 updates, 0 removals\n\n  \xe2\x80\xa2 Installing pyparsing (3.0.8)\n  \xe2\x80\xa2 Installing attrs (21.4.0)\n  \xe2\x80\xa2 Installing more-itertools (8.13.0)\n  \xe2\x80\xa2 Installing packaging (21.3)\n  \xe2\x80\xa2 Installing pluggy (0.13.1)\n  \xe2\x80\xa2 Installing py (1.11.0)\n  \xe2\x80\xa2 Installing wcwidth (0.2.5)\n  \xe2\x80\xa2 Installing pytest (5.4.3)\n\nInstalling the current project: poetry_demo (0.1.0)\n\n$ poetry check\nAll set!\n

\n

我认为这应该让我做好准备？让我们运行内置测试：

\n

只是为了验证该设置对于任何查看此内容的人来说是否正确：

。

\n

$ cat tests/test_poetry_demo.py\nfrom poetry_demo import __version__\n\n\ndef test_version():\n    assert __version__ == '0.1.0'\n

\n

。

\n

$ cat src/poetry_demo/__init__.py\n__version__ = '0.1.0'\n

我也尝试过没有--src但它是一样的。

目前使用的pytest版本已经过时，无法与 python3.10 一起使用。您必须使用进行更新。poetrypoetry newpytestpoetry add --dev pytest@latest

从诗歌 1.2 开始，诗歌在通过 初始化项目时将不再定义任何默认依赖项poetry new。
