Python（自制）在Sqlite上返回错误

Question

I have Python 2.7.6 and Python 3.3.4 installed through homebrew. I ran into some errors when trying to use Sqlite and I traced the error to a "symbol not found" error. Please see the trace below.

How can I get this thing to work?

>>> import sqlite3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sqlite3/__init__.py", line 24, in <module>

edit: Sqlite3 also seems to be properly installed (sqlite-3.8.3 already installed).

On a sidenote, why does homebrew stick with Python 2.7.6 while the Python website offers version 2.7.8 for download?

Answer 1

You need to run brew update ; both the sqlite formula and the python formula have seen numerous updates.

Python 2.7.8 has been available since July 2nd , for example. Your SQLite problems have probably long been solved with updates as well.

It is always a good idea to run brew doctor when you are having problems with Homebrew-supplied software; the output would have told you to run brew update too:

$ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Your Homebrew is outdated.
You haven't updated for at least 24 hours. This is a long time in brewland!
To update Homebrew, run `brew update`.
