We just upgraded to pants 2.6. We're using the wrapper so I just changed the version in

pants.toml

. That worked as expected on my Linux machine but my coworker on OSX is seeing the following:

It's strange that pip can't find

pantsbuild.pants

above 2.4.2. I checked PyPi and it's there. Any ideas?

Hi! What version of macos are they?

Thanks for the quick reply. She is, indeed, running an old version of OSX. She's going to try to upgrade tonight. I'll let you know if that doesn't solve the problem.

Cool, thanks Oliver! As mentioned in the thread, we should make this be an eager error in the

./pants

bash script - this is the third time it's tripped someone up this month alone 😮
