I was going through the Flow installation and when I typed sumo --version into the terminal I got the following error message:
dyld: Library not loaded: /usr/local/opt/proj/lib/libproj.13.dylib
Referenced from: /Users/apple/sumo_binaries/bin/sumo
Reason: image not found
I've tried reinstalling sumo but the problem persisted. How can I solve this issue?
I've found a fix for the problem.
Type the following into the terminal:
ln -s /usr/local/opt/proj/lib/libproj.15.dylib /usr/local/opt/proj/lib/libproj.13.dylib
Open up the directory mentioned above and make sure both libraries show (even if one of them is a shortcut) and rerun the sumo installation.
Note: you may have to change the paths depending on where your libproj.15.dylib is located.
