Libssl and libcrypto causing dyld: Library not loaded: /usr/lib/libpq.5.dylib
Question:
I recently uninstalled postgresql and installed pyscopg2 via pip.
I know there’s some trickery involved with libcrypto and libssl
Currently i have them symlinked to:
$ ls -lah libssl.*
-rwxr-xr-x 1 root wheel 402K Aug 28 11:06 libssl.0.9.7.dylib
-rwxr-xr-x 1 root wheel 589K Aug 28 11:06 libssl.0.9.8.dylib
lrwxr-xr-x 1 root wheel 55B Nov 29 23:38 libssl.1.0.0.dylib -> /usr/local/Cellar/openssl/1.0.1c/lib/libssl.1.0.0.dylib
lrwxr-xr-x 1 root wheel 55B Nov 30 02:25 libssl.dylib -> /usr/local/Cellar/openssl/1.0.1c/lib/libssl.1.0.0.dylib
/usr/lib
$ ls -lah libcrypto.*
-rwxr-xr-x 1 root wheel 2.1M Aug 28 11:06 libcrypto.0.9.7.dylib
-rwxr-xr-x 1 root wheel 2.6M Aug 28 11:06 libcrypto.0.9.8.dylib
-r-xr-xr-x 1 root wheel 1.6M Oct 31 22:12 libcrypto.1.0.0.dylib
lrwxr-xr-x 1 root wheel 58B Nov 30 02:27 libcrypto.dylib -> /usr/local/Cellar/openssl/1.0.1c/lib/libcrypto.1.0.0.dylib
whereby I installed openssl via ports
Now when I run arc diff, I am getting the infamous
$ arc diff
dyld: Library not loaded: /usr/lib/libpq.5.dylib
Referenced from: /usr/bin/php
Reason: image not found
Trace/BPT trap: 5
There are a few answers here in SO which talks about symlinking these libs to the postgresql install directory. Obviously, this won’t work for me.
What should I do?
Answers:
Turns out /usr/lib/libpq.5.dylib was absent but /usr/lib/libpq.5.4.dylib was not.
sudo ln -s /usr/lib/libpq.5.4.dylib /usr/lib/libpq.5.dylib
fixed the issue.
Not unlike @Pablo Marambio, I fixed this issue by adding the following line to ~/.profile:
export DYLD_LIBRARY_PATH=/Library/PostgreSQL/9.3/lib:$DYLD_LIBRARY_PATH
For Postgres.app v9.3.5.0 (presumably others too) I added the following line instead:
export DYLD_LIBRARY_PATH=/Applications/Postgres.app/Contents/Versions/9.3/lib:$DYLD_LIBRARY_PATH
Then, of course, run source ~/.profile
To resolve this, I had to uninstall postgresql and then install again.
$ brew uninstall postgresql
$ brew update
$ brew install postgres
just use the below commands in your terminal
(use the proper postgresql version)
$ brew unlink postgresql@14
$ brew link libpq --force

I got the error
Library not loaded: ‘/usr/local/opt/postgresql/lib/libpq.5.dylib’
Reason: tried: ‘/usr/local/opt/postgresql/lib/libpq.5.dylib’ (no such file), ‘/usr/local/lib/libpq.5.dylib’ (no such file), ‘/usr/lib/libpq.5.dylib’ (no such file)
when running a Django project and to fix it I had to uninstall the pip packages:
pip uninstall psycopg2
pip uninstall psycopg2-binary
and then install them again:
pip install psycopg2
pip install psycopg2-binary
And this made the project run without the error.
I had to do this for postgresql 14 + brew
sudo ln -s /opt/homebrew/opt/postgresql@14/lib/postgresql@14/libpq.5.dylib /opt/homebrew/opt/postgresql/lib/libpq.5.dylib
I’m using poetry so to solve it on my fastapi project, I had to do this to fix it:
poetry remove psycopg2
poetry add psycopg2
