Hi, all.

I am trying to install Falcon assembly on Mac. But I am not so sure how to handle this error....... The installation goes fine until this point

cd /Users/Desktop/software/FALCON-integrate/FALCON; pip uninstall -v .; pip install -v --user --edit .

When I was installing Falcon on Linux, I had problems with permission and ended up running the following commands .

su -l 
source env.sh
make -j all

But on mac, it is not working. So I am not so sure what to try next. Has anyone installed Falcon on mac?

It's this line:

pkg_resources.VersionConflict: (networkx 1.11 (/Users/Desktop/software/FALCON-integrate/fc_env/lib/python/site-packages), Requirement.parse('networkx>=1.7,<=1.10'))

Looks like it wants networkx with at least version 1.7 while you have 1.11

Ah, Thank you! It worked with easy_install!

sudo easy_install networkx 
sudo su 
make -j all
