Bench Update Error - "python egg_info"

Hello All,

I get the following error when I try to run bench update within my frappe-bench folder on mac osx.
I reinitialised my frappe app recently (deleted .git folder and ran git init again). I wonder if this has anything to do with the error.
I’d appreciate any tips to get past this error.

Requirement already up-to-date: pip in ./env/lib/python2.7/site-packages
Command "python egg_info" failed with error code 1 in /private/var/folders/wr/3cw2rk7n0zldjj_gnfjzmjwh0000gn/T/pip-build-hmhc8N/frappe/

I fixed this by doing the following from my frappe-bench folder:

./env/bin/pip install -e ./apps/frappe
