Question

Hey all getting this error when trying to generate a Python lockfile ```ERROR Could not find a version that satisfies the requirement pandas==1 5 2 ERROR No matching distribution found for pandas==1 5 2``` When I remove that dependency from my `requirements txt` the lockfile generation works This version of pandas also definitely exists I have specified in my indexes field under ` python repos ` Also weird is that there are other dependencies that depend on pandas and it is able to locate a much older version but there s no requirement that should prevent installation of this specific version

It is saying it can t find that version that also matches all the other constraints There is probably an interpreter constraint or a version constraint on another dep that is making v1 5 2 be marked incompatible

this kind of error is in most case due to to wide range of python interpreter constraints defined in pants toml <https www pantsbuild org docs python interpreter compatibility> so for example if you allow python 3 6 pants will try to find a version wheel aka distribution for pandas that satisfies both the interpreter constraints 3 6 and the pandas version 1 5 2 and if that fails that is the error you will be getting
