Import Error: 没有名为“ Queue”的模块

我试图导入 requests模块，但我得到了这个错误 我的 Python 版本是在 ubuntu 14.04上运行的3.4

>>> import requests
Traceback (most recent call last):
File "/usr/local/lib/python3.4/dist-packages/requests/packages/urllib3/connectionpool.py", line 10, in <module>
from queue import LifoQueue, Empty, Full
ImportError: cannot import name 'LifoQueue'


During handling of the above exception, another exception occurred:

I solve the problem my issue was I had file named queue.py in the same directory

Queue is in the multiprocessing module so:

from multiprocessing import Queue

import queue is lowercase q in Python 3.

Change Q to q and it will be fine.

(See code in https://stackoverflow.com/a/29688081/632951 for smart switching.)

In my case it should be:

from multiprocessing import JoinableQueue

Since in python2, Queue has methods like .task_done(), but in python3 multiprocessing.Queue doesn't have this method, and multiprocessing.JoinableQueue does.

I run into the same problem and learn that queue module defines classes and exceptions, that defines the public methods (Queue Objects).

Ex. 

workQueue = queue.Queue(10)
小开

It's because of the Python version. In Python 2.x it's import Queue as queue; on the contrary in Python 3 it's import queue. If you want it for both environments you may use something below as mentioned here

try:
import queue
except ImportError:
import Queue as queue
小开

I just copy the file name Queue.py in the */lib/python2.7/ to queue.py and that solved my problem.
