Fwiw I updated the PEX CLI because I thought it would fix the "exec format error" coworkers were getting when running just "pants" (no goals, just pants). Unfortunately, coworkers have been reporting that they still run into this problem even after merging in that fix and clearing their cache. I experienced another more fun version of this bug where the -sE was getting cutoff and so it still "worked" but it leaked my pythonpath env variable into sys.argv making pantsd invalidate on every file change.
