PyCharm Pro & OS X 10.11 El Capitain

I am unable to create a Django project using PyCharm 5.0.3 Pro.

When I try to create a project I get an error popup:-

/var/folders/yb/3fwr_8_n3z56lwnmp_hrl6x80000gn/T/tmpfOTS8Mpycharm-management/pip-7.1.0/setup.py install

40:357: execution error: warning: build_py: byte-compiling is disabled, skipping.

40:357: execution error: warning: build_py: byte-compiling is disabled, skipping.

Can you help?
