maybe pytest-benchmark should install it if missing?

[ionelmc]

pip should do that, hmmm

can you paste some install logs? (eg: pip install pytest-benchmark)

Do you happen to use a very old pip (that don't support environment markers)?

[ionelmc]

I think pip < 6.0 is not going to correctly install that dep - you need to manually specify it (pip install statistics). Or just upgrade pip (better)
