Installation issue mac

[stefanknegt]

When I try to install bcolz, either using pip or from source, I get one of the following errors:

error: command 'gcc' failed with exit status 1 error: command 'xcrun' failed with exit status 1

Often this is caused by not having Xcode or Xcode select installed, but I have both installed and have no issues with other packages. Does anyone have an idea how to fix this?

Somehow this issue is not present when I install version 1.2.0 instead of 1.2.1.

have you tried to update pip setuptools and wheel before trying to install bcolz? python -m pip install pip setuptools wheel -U

Yes I've tried that, but no luck. I even reinstalled python and tried different versions of python, but nothing (except installing 1.2.0) seems to work.
