Installazione di MySQL-python su mac

Question

Sto usando OSX 10.8 e PyCharm per lavorare su un progetto di sviluppo Python. Ho installato MySQL-python per Mac utilizzando le istruzioni sul sito

http://blog.infoentropy.com/MySQL-python_EnvironmentError_mysql_config_not_found

Tuttavia, l'esecuzione il progetto mi dà questo errore:

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: dlopen(/Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so, 2): Symbol not found: _mysql_affected_rows

    Expected in: flat namespace 
in /Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so 

Il file menzionato int l'errore esistente al posizione - /Users/ashishagarwal/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg-tmp/_mysql.so

L'intero messaggio di errore è -

Answer 1

È necessario installare MySQL attraverso Homebrew prima, per ottenere il lavoro python-mysql correttamente su OS X.

pip uninstall MySQL-python 
brew install mysql 
pip install MySQL-python 

Answer 2

Assicurarsi di avere la versione più recente di Xcode tra cui Command Line Tools. Ho semplicemente scaricato l'aggiornamento da 2 GB dall'app store. Ho avuto un problema simile, in particolare this, e questo l'ha risolto.

Cheers!
