python - 如何添加路径以便python可以找到程序？

Question

我尝试通过 import 函数将 sqlite 与 python 一起使用，但看起来 python 找不到 sqlite。

我的 sys.path 包含以下内容:

['', '/usr/local/share/python', '/usr/local/Cellar/python/2.7.3/lib/python2.7/site-packages/distribute-0.6.26-py2.7.egg', '/usr/local/Cellar/python/2.7.3/lib/python2.7/site-packages/pip-1.1-py2.7.egg', '/usr/local/Cellar/python/2.7.3/lib/python27.zip', '/usr/local/Cellar/python/2.7.3/lib/python2.7', '/usr/local/Cellar/python/2.7.3/lib/python2.7/plat-darwin', '/usr/local/Cellar/python/2.7.3/lib/python2.7/plat-mac', '/usr/local/Cellar/python/2.7.3/lib/python2.7/plat-mac/lib-scriptpackages', '/usr/local/Cellar/python/2.7.3/lib/python2.7/lib-tk', '/usr/local/Cellar/python/2.7.3/lib/python2.7/lib-old', '/usr/local/Cellar/python/2.7.3/lib/python2.7/lib-dynload', '/usr/local/Cellar/python/2.7.3/lib/python2.7/site-packages', '/usr/local/Cellar/python/2.7.3/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg-info', '/usr/local/Cellar/python/2.7.3/lib/python2.7/site-packages/IPython/extensions']

但是sqlite列在usr/lib中。

编辑:
按照建议，我尝试导入 sqlite3，但 python 返回此错误:

dlopen(/usr/local/Cellar/python/2.7.3/lib/python2.7/lib-dynload/_sqlite3.so, 2): Library not loaded: /usr/local/lib/libsqlite3.0.8.6.dylib
  Referenced from: /usr/local/Cellar/python/2.7.3/lib/python2.7/lib-dynload/_sqlite3.so
  Reason: image not found

如何加载sqlite？

Answer 1

无需向模块搜索路径添加任何内容； SQLite 模块附带 Python 标准库。但是，您拼错了模块的名称，它被称为 sqlite3 (注意末尾的 3):

Python 2.7.3 (default, Oct 22 2012, 06:12:32) 
[GCC 4.2.1 Compatible Apple Clang 3.1 (tags/Apple/clang-318.0.58)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
>>> sqlite3.connect(':memory:')
<sqlite3.Connection object at 0x105354200>

如果仍然出现错误，则说明您的自制程序安装已损坏；你可能遇到this bug 。运行:

brew rm sqlite python
brew install python

修复。
