Attention
Turns out that system library changes also affect the compilation process of psycopg2. Overall, not their fault but definitely something to keep in mind. The original article is below.
I had a lot of fun today after upgrading psycopg2 to 2.5.1. I wasplaying around with SQLAlchemy so I ran the normal commands forgetting a Postgres database up and running.
Postgresql Mac Client
Postgres.app is a simple, native macOS app that runs in the menubar without the need of an installer. Open the app, and you have a PostgreSQL server ready and awaiting new connections. Close the app, and the server shuts down. PostgreSQL can also be installed on macOS using Homebrew. Please see the Homebrew documentation. # Create the rails project rails new projectname -database=postgresql cd projectname # Create the Postgres user createuser projectname # Create the databases createdb -Oprojectname -Eutf8 projectnamedevelopment createdb -Oprojectname -Eutf8 projectnametest # Create some models/controllers etc rails generate controller site rails generate model # Run migrations rake db:migrate # Start the. Postgres.app is the easiest way to get started developing with Postgres on the Mac. Open the app, and you have a local Postgres database ready and awaiting new connections. Close the app, and the server shuts down. It is available for free download today, and will be available on the Mac App Store pending Apple's approval.
What the hell is that?!?
First thing I did is jump into some Google searches. Ironically thefirst result hit was a StackOverflow question that ultimately solved myissue but I wasn’t settling at the time for an easy solution. This had workedseconds before on another application. Why wasn’t it working now?
I jumped over to another Django (1.4) application I had running and triedupgrading psycopg2. Upgrade and build worked fine, but now I had the same erroras with the SQLAlchemy application. Looked like psycopg2 version was the culprithere. I tried downgrading to the previous version of psycopg2 (2.4.5). Now thesame damn error with the previous version. This can’t be good.
Another project I had (running Django 1.5) had the same (old, 2.4.5) version ofpsycopg2. Directly copying it to the existing (Django 1.4) project worked fine.It looks like psycopg22.4.5 had been updated at some point and this is whyfresh installs were failing out with this

error.Finally I was at the point where I thought soft linking libraries on my systemwas a decent way to solve the problem. Postgres.app by the niceguys at Heroku is where all my PostgreSQL related stuff lives. Thepath for the two required dylibs is
/Applications/Postgres.app/Contents/MacOS/lib/libssl.1.0.0.dylib
and /Applications/Postgres.app/Contents/MacOS/lib/libcrypto.1.0.0.dylib
. Both of these need to be linked into /usr/local
. There is alreadya linked file (libssl.dylib
and libcrypto.dylib
) in that folder on my systemthat point to libssl.0.9.8.dylib
and libcrypto.0.9.8.dylib
respectively. Iwouldn’t recommend changing these so I simply softlinked the new 1.0.0 versionsinto that folder. These commands require sudo
for obvious reasons.Flipping back to my Django 1.4 app I can confirm it works as expected. MySQLAlchemy application works too now.
Other points for troubleshooting
The error here is pretty explicit. Something was expected that could not befound. Google is your friend, and often some of the first results are OK. Noneed to feel that a spontaneous problem shouldn’t be resolved by a little softlinking.
That said, it’s important to realize that when you push a package at a versionnumber it should be frozen. I should be able to bring down the exact samecode by specifying what version number of a package. Have you changed orimproved something? Great! Time to increment that minor version number.
