Question

Should setuptools always be present Because it doesn t seem to be I m getting some import errors for `pkg resources` which is in `setuptools` a dep `flex` does not declare a dep on `setuptools` they think its std lib <https github com pipermerriam flex blob master flex init py L6> What are my options for getting pants to include setuptools in this case

So do I have to add setuptools to `python library dependencies = ` even though it is a transitive dep

Create an inlined python requirement library rather than putting it in requirements txt Add to its dependencies field the path to setuptools target eg 3rdparty python setuptools <https www pantsbuild org v2 5 docs python third party dependencies inline requirements|https www pantsbuild org v2 5 docs python third party dependencies inline requirements> gt rather than putting it in requirements txt It s necessary to remove from requirements txt so that you don t have two targets referring to the same requirement which would disable dependency inference for flex because it would be ambiguous which you want to use The generate constraints sh script will still do the right thing

Ah Ok I ll probably leave a comment in the requirements file Is it better to put that flex python requirement library in the top level BUILD or in the file next to where it is used

I d probably say the BUILD where your requirements txt is that That way it s more discoverable if other modules start using it in the future
