Searching both external and within issues found several similar issues nothing helpful so far. I've tried more-and-less setuptools config blocks without any success (currently less as directed in some related discussions as well as setuptools docs). Thanks in advance! |

Is this with the system pip? If so, can you reproduce with pip from PyPI? I believe Ubuntu patch the version of pip they supply. |

@sarnold [testenv]
skip_install = true
setenv =
COVERAGE_FILE = .coverage.{envname}
PYTHONPATH = {toxinidir}/srcIf you look closely at your log, pip is picking up this "installed" pyserv and refuses to uninstall it as it's outside the virtual environment directory. This results in the actual pyserv installation being shadowed (while the PYTHONPATH envvar is set). I haven't looked at your tox configuration that closely, but this seems like poor practice...? You should test against the built distribution to ensure your packaging configuration is not faulty. If not, you may end up missing packaging blunders that your users will encounter. |

"Well I'll be a dirty..." With all the environment isolation in newer Tox versions that seems like a bug, but removing that from setenv in the default [testenv] does indeed populate metadata for both Files and Location correctly when displayed from the [check] environment. Thanks for the eye/brain poke! |

I'm glad to have helped! |
Description
Scenario is installing locally built wheel into virtualenv in project checkout, with all metadata in pyproject.toml. Running
python -m pip show -f pyservdisplays incorrect data and claims "Cannot locate RECORD or installed-files.txt" when the RECORD file does indeed exist in the installed.dist-info/. TheFiles:list is empty and theLocation:displayed is not in the virtualenv site-packages (instead it displays thesrcdirectory in the project root.Expected behavior
The equivalent display when using setup.cfg for metadata, ie the list of files from virtualenv site-packages and the correct virtualenv location.
