无法在sys模块之前导入time。Python
我在打开ipython笔记本的时候遇到了一些问题,似乎在导入时间模块时出错了:
//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 *

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'
奇怪的是(对我来说),我在导入时间模块之前,必须先导入sys模块,否则就加载不进去!

这个问题发生在我清理了我的.bash_profile和.profile文件,删除了那些注释的行之后。 如果有人能帮我解释一下,我会非常感激。
谢谢。

你有一个本地文件叫做 time.py
,它和内置的时间类型冲突了。你需要把这个文件删除或者改个名字。你可以通过输入以下命令来查看这个冲突模块的文件名:
import time
print time
在你第二次导入的时候,你收到了一个警告,而不是错误。虽然 import time
这一行是成功的,但它触发了代码,导致错误的 time
模块被加载。再次导入的时候,它使用了已经导入的模块对象,即使它重新执行了导入,警告通常只会记录一次。
