mac - pip install pymssql error

Question

I use Mac (OS X 10.11.5). I want to install module pymssql for python. In Terminal.app, I input sudo -H pip install pymssql, pip

Answer 1

The top voted solution did not work for me as brew did not link the older version of freetds on its own. I did this to solve the problem:

brew unlink freetds; 
brew install freetds@0.91;
brew link --force freetds@0.91

Answer 2

All the solutions above work well . Just one word of caution , the setup.py for pymssql pip install pymssql expects that Homebrew has installed Freetds at /sw

if sys.platform == 'darwin':
    fink = '/sw'

This was not the case in my machine so I had to use the work around here :

1. Manually download the .tar file for pymssql
2. change this in setup.py file to point fink to freetds location
3. Then run python setup.py install

Answer 3

I was able to work around this by reverting to an older version of FreeTDS through Homebrew before running the pip install.

brew unlink freetds; brew install homebrew/versions/freetds091

"brew install homebrew/python/pymssql" also worked but will install older 2.1.1 as of today.
