我正在尝试在OS X 10.5的virtualenv下使用SQLAlchemy,但似乎无法将其加载到任何地方。
这就是我做过的事情
mkvirtualenv --no-site-packages test
easy_install sqlalchemy
我尝试从解释器导入sqlalchemy,一切正常,但如果我尝试从python脚本导入sqlalchemy,我会收到以下错误:
以下是IBM
的教程脚本from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Table, Column, Integer, String, MetaData, ForeignKey
Base = declarative_base()
class Filesystem(Base):
__tablename__ = 'filesystem'
path = Column(String, primary_key=True)
name = Column(String)
def __init__(self, path,name):
self.path = path
self.name = name
def __repr__(self):
return "<Metadata('%s','%s')>" % (self.path,self.name)
我尝试运行'python test.py',这就是结果:
$ python test.py
Traceback (most recent call last):
File "test.py", line 4, in <module>
from sqlalchemy import Table, Column, Integer, String, MetaData, ForeignKey
File "/Users/grant/Development/Aircraft/sqlalchemy.py", line 3, in <module>
from sqlalchemy.ext.declarative import declarative_base
ImportError: No module named ext.declarative
这是我的sys.path
中的内容>>> import sys
>>> print '\n'.join(sys.path)

关于发生了什么的任何想法?
答案 0 :(得分:8)
我修复了我自己的问题...我在我工作的同一个文件夹中有另一个名为sqlalchemy.py的脚本,这样就搞砸了所有内容。
