python - pytest-xdist: LookupError: setuptools-scm was unable to detect version -


when installing pytest-xdist, i'm getting error:

i able install pytest-xdist before, i'm not sure changed :(

it looks you're hitting https://github.com/pypa/setuptools_scm/issues/164. workaround can pin setuptools-scm previous version in requirements.txt so:

setuptools_scm == 1.15.0

edit: issue has been fixed upstream , new version of setuptools-scm has been released (1.15.4). should not see issue anymore, without pinning version.
