Question

我在加载ipython笔记本时遇到问题，导入时间似乎有误：

//anaconda/python.app/Contents/lib/python2.7/logging/__init__.py:26: RuntimeWarning: import threads:        
cannot import name time
(ImportError: cannot import name time)
import sys, os, time, cStringIO, traceback, warnings, weakref, collections
Traceback (most recent call last):
File "//anaconda/bin/ipython", line 4, in <module>
from IPython import start_ipython
File "//anaconda/lib/python2.7/site-packages/IPython/__init__.py", line 45, in <module>
from .config.loader import Config
File "//anaconda/lib/python2.7/site-packages/IPython/config/__init__.py", line 16, in <module>
from .application import *
File "//anaconda/lib/python2.7/site-packages/IPython/config/application.py", line 23, in <module>
import logging
File "//anaconda/python.app/Contents/lib/python2.7/logging/__init__.py", line 95, in <module>
_startTime = time.time()
AttributeError: 'module' object has no attribute 'time'

奇怪（对我来说），我也无法将时间模块加载到python中，除非我还导入了sys！

这是在我通过删除注释掉的行来清理我的.bash_profile和.profile之后发生的。任何帮助/解释都将非常感激。

感谢。

您有一个名为time.py的本地文件，它掩盖了内置类型。删除或重命名它。您可以通过输入以下内容来查看屏蔽模块的文件名：

import time
print time

在第二次导入中，您收到了警告，而不是错误。 import time行工作，但它触发的代码也会因正在加载的错误time模块而跳闸。再次导入它会重新使用已导入的模块对象，即使它确实再次运行导入，警告也只会记录一次。

在sys模块之后才能导入时间。蟒蛇
