如何在python 3.x中使pip安装python 2.x模块

Question

我想使用pip安装邮件库，但是它导入了Queue模块，该模块已在python 3中重命名为queue，如何使用pip下载它？

Answer 1

Answer: You cannot! Why would you even consider such thing?

This why so many project still use Python 2.7 and not 3.4, because so many modules are not ported yet. However, more and more are, especially the famous ones.

The only thing you can do, is to find an equivalent / replacement module doing the same thing.

Update:

For creating queues, you could leverage the Deque (collections.deque) or find some implementations of queues using deque.
