问题描述

我正在尝试使用 pyzmq 运行一段简单的代码.我使用的是 Python 2.7 和 pyzmq 14.5

I'm trying to run a simple piece of code using pyzmq. I am using Python 2.7 and pyzmq 14.5

$ python --version
Python 2.7.6
$ sudo find /usr -name "*pyzmq*"
/usr/local/lib/python2.7/dist-packages/pyzmq-14.5.0.egg-info
/usr/lib/python2.7/dist-packages/pyzmq-14.0.1.egg-info

以下是我要运行的代码:

Following is the code i'm trying to run:

import zhelpers

context = zmq.Context.instance()
server = context.socket(zmq.ROUTER)
server.bind("tcp://*:5678")

while (1):
    address, empty, data = server.recv_multipart()

    print("address = %s, data = %d" % (address, int(data)))

    data_i = int(data) + 10
    server.send_multipart([
        address,
        b'',
        str(data_i),
    ])

但是，我收到以下错误并且不知道如何解决此问题:

But, I'm getting following error and got no clue how to fix this:

Traceback (most recent call last):
  File "reqrep_server.py", line 8, in <module>
    import zhelpers
  File "/home/arun/pyzmq_server/zhelpers.py", line 11, in <module>
    import zmq
  File "/home/arun/pyzmq_server/zmq/__init__.py", line 66, in <module>
    from zmq import backend
  File "/home/arun/pyzmq_server/zmq/backend/__init__.py", line 41, in <module>
    reraise(*exc_info)
  File "/home/arun/pyzmq_server/zmq/backend/__init__.py", line 29, in <module>
    _ns = select_backend(first)
  File "/home/arun/pyzmq_server/zmq/backend/select.py", line 27, in select_backend
    mod = __import__(name, fromlist=public_api)
  File "/home/arun/pyzmq_server/zmq/backend/cython/__init__.py", line 6, in <module>
    from . import (constants, error, message, context, socket, utils, _poll, _version, _device)
ImportError: cannot import name constants

我已经复制了整个 zmq 文件夹并将其作为我的 .py 文件放置在关卡中.

I've copied the whole zmq folder and placed it in the level as my .py file.

请帮忙！

我已经按照指示删除了这两个版本的 pyzmq 并重新安装了最新的 pyzmq(这次捆绑了 libzmq)此处.

I've removed those two versions of pyzmq and reinstalled latest pyzmq (with libzmq bundled this time) as instructed here.

$ sudo find /usr -name "*pyzmq*"
/usr/local/lib/python2.7/dist-packages/pyzmq-14.7.0-py2.7.egg-info

$ sudo find /usr -name "*libzmq*"
/usr/local/lib/libzmq.so
/usr/local/lib/libzmq.la
/usr/local/lib/libzmq.so.5.0.0
/usr/local/lib/pkgconfig/libzmq.pc
/usr/local/lib/libzmq.so.5
/usr/local/lib/python2.7/dist-packages/zmq/libzmq.so
/usr/local/lib/python2.7/dist-packages/zmq/backend/cython/libzmq.pxd
/usr/local/lib/libzmq.a

但这并不能解决问题.我遇到了同样的错误！

But this doesn't solve the problem. I'm getting the same error!
