Update dist_info location generation to account for build tags by rydrman · Pull Request #86 · bazel-contrib/rules_python

The pep-427 spec that is being followed when discovering dist_info data in python wheels allows for an optional build tag to exist.

Previously this was not taken into account and could make the dist_info appear missing when a build tag was used.

These changes update the way the dist_info path is generated to allow for the case where a build tag is included.
