Calling knife returns 'Could not locate Gemfile' message

Chef Development Kit Version: 0.1.0

Could not locate Gemfile
[21:12:09] ~ > which knife
/usr/bin/knife

lrwxr-xr-x  1 root  wheel  21 Jun 23 21:09 /usr/bin/knife@ -> /opt/chefdk/bin/knife
[21:12:14] ~ > echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/packer

Any ideas why this may be happening? I included some command calls to show the path is set correctly. I am on a mac. Let me know if you want me to provide more information.

Thanks,
Jay

This was due to having this in my .bash_profile
alias knife='bundle exec knife'
