I suppose you're using this: https://anaconda.org/conda-forge/pytest-benchmark? It would appear they pin an older pytest-benchmark release.

I suppose this is the source https://github.com/conda-forge/pytest-benchmark-feedstock?

[dazza-codes]

Hmmm, might be another case of conda vs. pip inconsistencies. Using a pip install after creating/activating a conda env seemed to solve the problem. Close at will.

I created https://github.com/conda-forge/pytest-benchmark-feedstock/issues/6 for the conda-forge package. I think this issue can be closed.

Facing the same error here.

[ionelmc]

@TejasAvinashShetty pip install the latest or use whatever was suggested above?

Just to add to this, it still seems to be an issue since today I got the exact same error when I installed the same conda-forge pytest packages as OP.

Versions:

• macOS Mojave 10.14.5 (18F203)
• miniconda3 - conda 4.7.5
• pytest 5.0.1
• pytest-xdist-1.29.0
• pytest-forked-1.0.2
• pytest-datadir-1.3.0
• pytest-voluptuous-1.1.0
• pytest-benchmark-3.2.2
• pytest-cov-2.7.1
• pytest-mock-1.10.4

I have the list of packages in a plaintext file pytest_reqs.txt:

pytest
pytest-benchmark
pytest-cov
pytest-datadir
pytest-forked
pytest-mock
pytest-runner
pytest-xdist

Got the error after installing with:

conda install -c conda-forge --file pytest_reqs.txt

Fixed it with:

conda uninstall -y pytest
pip install -r pytest_reqs.txt

Edit: using python version 3.7.3

[TejasAvinashShetty]

@TejasAvinashShetty pip install the latest or use whatever was suggested above?

Yes it works
