Root Cause

The [tool:pytest] section was written in pytest.ini (which expects [pytest]), or the pyproject.toml lacks the required [tool.pytest.ini_options] header.

generic

中文

在 pytest.ini 中写入了 [tool:pytest] 段（应使用 [pytest]），或 pyproject.toml 缺少必需的 [tool.pytest.ini_options] 头。

Workarounds

  1. 98% success 
    # pytest.ini
[pytest]
addopts = -ra

# pyproject.toml
[tool.pytest.ini_options]
addopts = '-ra'

# setup.cfg
[tool:pytest]
addopts = -ra
  2. 90% success 
    ls pytest.ini tox.ini setup.cfg pyproject.toml
# Keep exactly one with the correct section; delete or empty the others.

Dead Ends

Common approaches that don't work:

  1. 75% fail

    pytest reads only one config file and ignores the duplicate; the parse error remains or config is silently dropped.

  2. 60% fail

    setup.cfg expects [tool:pytest] but other tools may also read it; renaming alone does not fix the section header inside.
