Can't open lib 'ODBC Driver 13 for SQL Server'? Sym linking issue?

Question

When I try to connect to a sql server database with pyodbc (on mac):

import pyodbc

server = '####'
database = '####'
username = '####@####'
password = '#####'
driver='{ODBC Driver 13 for SQL Server}'

pyodbc.connect('DRIVER='+driver+';SERVER='+server+';PORT=1443;DATABASE='+database+';UID='+username+';PWD='+password)

I get the following error:

Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'ODBC Driver 13 for SQL Server' : file not found (0) (SQLDriverConnect)")

When I path in the actual driver location:

driver='/usr/local/lib/libmsodbcsql.13.dylib'

It starts working!

My odbcinst.ini looks like this:

[ODBC Driver 13 for SQL Server]
Description=Microsoft ODBC Driver 13 for SQL Server
Driver=/usr/local/lib/libmsodbcsql.13.dylib
UsageCount=1

How can I get my reference to driver='{ODBC Driver 13 for SQL Server}' to start working again?

I initially used this guide to install the driver. And I'm using anaconda on Mac Sierra if that helps?

Answer 1

Running:

odbcinst -j

It yielded:

unixODBC 2.3.4
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /Users/emehex/.odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8

Instead of copying the files to the /etc/ directory (not sure why unixODBC thought they were there) I created a symbolic link to each file:

sudo ln -s /usr/local/etc/odbcinst.ini /etc/odbcinst.ini
sudo ln -s /usr/local/etc/odbc.ini /etc/odbc.ini

This solved the problem.
