Hello,
I'm trying to install the Cartopy package for use with matplotlib in my virtual env, however there seems to be a problem with the Proj4 version... I'm not sure how to fix this.
Collecting Cartopy==0.14.0 (from -r requirements.txt (line 2))
Using cached Cartopy-0.14.0.tar.gz
Complete output from command python setup.py egg_info:

'.'.join(str(v) for v in PROJ_MIN_VERSION), ))
Proj4 version 0.0.0 is installed, but cartopy requires at least version 4.9.0.
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-cfi_la_6/Cartopy/
Any help is appreciated.
