Trying to setup postgres with the postgres mac app and hit this error, which I haven\'t been able to solve. Any thoughts?
ImportError: dlopen(/Users/Crai
I had the same error because of upgrading Postgres.app (from 9.3 to 9.4).
The solution was to delete the pip cache wheels because they were pointing to Postgres.app version 9.3.
I've found the according psycopg wheel cache files this way
grep -r psycopg ~/.pip/cache
and deleted the directory I've found with the last command.
