我无法在python中找到一个模块,尽管easy_install说已经安装了.任何想法如何解决这个问题？
$ python -c "from flaskext.sqlalchemy import SQLAlchemy"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named sqlalchemy
$ python -V
Python 2.7
$ sudo easy_install sqlalchemy

$ sudo pip install SQLAlchemy --upgrade要求已经是最新的:/usr/lib/python2.7/site-packages中的SQLAlchemy清理...
虽然pip说已经安装了.但我在sys.path输出中找不到它们.
$ sudo python -c "import sys;print sys.path" ['',
