"PULP_VERSION = pkg_resources.require('pulp-server')[0].version" was introduced in https://github.com/pulp/pulp/commit/19a527036d4e1b3ed06037ada70a5de5cd556940 and was released with 2.20.0. I checked 2.19.1 RPM does not include this line. Obviously client side will not have pulp-server package and will thus fail.
