tox 命令在 windows 中引发异常

Question

I have tox.ini like below in windows

[testenv:bootstrap]
deps =
    jinja2
    matrix
    tox
skip_install = true
commands =
    python ci/bootstrap.py --no-env
passenv =
    *
; a generative tox configuration, see: https://tox.readthedocs.io/en/latest/config.html#generative-envlist

[tox]
envlist =
    clean,
    check,
    docs,
    py38,
    report
ignore_basepython_conflict = true

[testenv]
setenv =
    PYTHONPATH={toxinidir}/tests
    PYTHONUNBUFFERED=yes
passenv =
    *
usedevelop = false
deps =
    pytest
    pytest-travis-fold
    pytest-cov
commands =
    {posargs:pytest --cov --cov-report=term-missing -vv tests}

[testenv:check]
deps =
    docutils
    check-manifest
    flake8
    readme-renderer
    pygments
    isort
skip_install = true
commands =
    python setup.py check --strict --metadata --restructuredtext
    check-manifest {toxinidir}
    flake8
    isort --verbose --check-only --diff --filter-files .

[testenv:docs]
usedevelop = true
deps =
    -r{toxinidir}/docs/requirements.txt
commands =
    sphinx-build {posargs:-E} -b doctest docs dist/docs
    sphinx-build {posargs:-E} -b html docs dist/docs
    sphinx-build -b linkcheck docs dist/docs

[testenv:report]
deps =
    coverage
skip_install = true
commands =
    coverage report
    coverage html

[testenv:clean]
commands = coverage erase
skip_install = true
deps =
    coverage

How to resolve my problem?

Answer 1

I have no simple solution but a guideline how to isolate the problem and how to fix it yourself.

In your tox.ini file a lot is going on. Especially in your check env you run 4 commands, and additionally it inherits from the generic testenv .

Change the order to your liking, but I would first...

• comment out the generic testenv as it does not seem to be necessary for the check env to work, and so you can avoid side effects, maybe caused eg by passenv = *
• comment out the last three commands in your check env and only run the first, then add the second and so on until you find the problematic command

The error message suggests one of the commands expects a directory, but was passed the path to the python interpreter.

From looking at your tox.ini I cannot see where the problem is at once, thus the instruction on how to debug the problem, see above.
