osx - Error importing MySQL package for Python -
i'm trying import mysql module python, more flask, though receive error. i'm using virtual environment application. here error:
traceback (most recent call last): file "../myapp/application.py", line 9, in <module> flask.ext.mysql import mysql file "/users/pavsidhu/documents/web-development/app/env/lib/python2.7/site-packages/flask/exthook.py", line 81, in load_module reraise(exc_type, exc_value, tb.tb_next) file "/users/pavsidhu/documents/web-development/app/env/lib/python2.7/site-packages/flaskext/mysql.py", line 3, in <module> import mysqldb file "/users/pavsidhu/documents/web-development/app/env/lib/python2.7/site-packages/mysqldb/__init__.py", line 19, in <module> import _mysql importerror: dlopen(/users/pavsidhu/documents/web-development/app/env/lib/python2.7/site-packages/_mysql.so, 2): library not loaded: /library/python/2.7/site-packages/_mysql.so referenced from: /users/pavsidhu/documents/web-development/app/env/lib/python2.7/site-packages/_mysql.so reason: image not found
i can see in error says library not loaded: /library/python/2.7/site-packages/_mysql.so
. i'm using virtual environment path incorrect. should /lib/python2.7/site-packages/_mysql.so
.
is there way change this? thanks.
edit:
i found there terminal command on osx change library location:
sudo install_name_tool -change libmysqlclient.18.dylib /lib/python2.7/site-packages/mysqldb/
though after hitting enter this:
usage: /library/developer/commandlinetools/usr/bin/install_name_tool [-change old new] ... [-rpath old new] ... [-add_rpath new] ... [-delete_rpath old] ... [-id name] input
i don't appear entering command wrong, issue?
as rule, try avoiding system python install plague. yes, basing virtualenvs on it. generate hard understand problems.
i recommend getting homebrew, installing python , mysql headers:
brew install python brew install mysql
and basing virtualenv on python brew:
virtualenv venv --python /usr/local/bin/python
i know, it's little more hoops jump through, make development process easier. not mention brew
great aid developer in own right.
i checked if worked, took me 2 minutes working mysqldb.
