Installing Packages on El Capitan

Trying to install pandas on El Capitan and I'm not getting too far. I've updated pip. I've tried to update setup tools, but that bombs too. I believe this is all related to security enhancements that aren't uniformly applied with an El Capitan upgrade install (rather than a clean install.) In any event, it seems that I'm not able to install Python packages now that I've upgraded to El Capitan (this is the first I've tried.) Have tried with 'sudo' and with '--user'.

Before researching further, I thought I'd stop by to see if anyone has already figured out the steps needed to overcome this issue.

Is this the error you're getting?

Code: Select all

Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-MixvQi/pandas/

If so, I think it's a problem with the pandas installer itself. I'm getting the same error, even though I've had no problem installing other packages on El Capitan. Try installing requests or twilio or django and see if you have a problem with other packages:

Also, looking at the info page for the pandas project, I think it may require Python 2.7.

Yup. I was able to install it for 2.7:

Thanks Joe! I didn't mean for someone else to research it for me.

That was one of the errors I was getting. I was just able to install twilio (I already had requests and django installed) so that appears to be exactly my issue. I'm surprised that pandas requires 2.7, but such is life. I'll need to find an alternative solution as I want to stick with 2.6.
