python - 使用 tox 运行脚本时诗歌依赖项不可用

Question

我有一个使用诗歌和毒药的Python项目。它有源代码、测试和脚本(juptext 笔记本)。我无法在脚本中导入开发依赖项，但可以在测试中导入。

当我遇到这个问题时，我创建了以下最小示例。一开始不行，后来我就摆弄了一下，现在可以了。因此，我删除了存在实际问题的项目，这样除了项目名称、位置、虚拟环境和 .git 目录之外，它是无法区分的，但这仍然不起作用。

更新删除所有构建工件和最小示例的 virtualenv 使其再次停止工作

更新将行scripts:诗安装添加到tox命令修复仅最小的示例

源代码、测试和脚本位于以下布局

foo
  +--foo
  |  +--__init__.py
  |
  +--tests
  |  +--__init__.py
  |  +--test_foo.py
  |
  +--scripts
  |  +--foo_script.py
  |
  +--pyproject.toml
  +--tox.ini

这些文件要么是空的，要么如下所示:

foo_script.py

import requests

test_foo.py

import requests
import pytest

def test():
    assert True

pyproject.toml

[tool.poetry]
name = "foo"
version = "0.1.0"
description = ""
authors = ["foo maker"]

[tool.poetry.dependencies]
python = "^3.7"
requests = "*"

[tool.poetry.dev-dependencies]
pytest = "^4.6"

[build-system]
requires = ["poetry>=0.12"]
build-backend = "poetry.masonry.api"

毒物.ini

[tox]
envlist = test, scripts
isolated_build = true
skipsdist = true

[testenv]
basepython = python3.7
whitelist_externals =
    pytest
    bash
commands =
    test: pytest
    scripts: bash -c 'python3 scripts/*.py'

当我运行 tox 时，我得到

test run-test-pre: PYTHONHASHSEED='4126239415'
test run-test: commands[0] | pytest

Answer 1

我相信类似以下的内容应该有效:

pyproject.toml

[tool.poetry]
name = "foo"
version = "0.1.0"
description = ""
authors = ["foo maker"]

[tool.poetry.dependencies]
python = "^3.7"
requests = "*"
#
pytest = { version = "^4.6", optional = true }

[tool.poetry.extras]
test = ["pytest"]

# [tool.poetry.dev-dependencies]
# use 'test' extra instead

[build-system]
requires = ["poetry>=0.12"]
build-backend = "poetry.masonry.api"

tox.ini

[tox]
envlist = test, scripts
isolated_build = true

[testenv]
basepython = python3.7
whitelist_externals =
    pytest
    bash
extras =
    test
commands =
    test: pytest
    scripts: bash -c 'for f in scripts/*.py; do python "$f"; done'
