无法安装Python的PyZMP -- 依赖问题
我在安装iPython的PyZMP依赖时遇到了麻烦。我尝试了很多方法,比如用pip或者brew,但最后还是手动安装了这个包,参考了这个答案。
现在,运行 pip list packages
后显示了以下内容:
pyzmq (14.2.0-dev)
pyzmq-static (2.2)
(我也尝试过使用pyzmq-static)。
另外,我的python eggs明显在正确的位置:
ls /usr/local/lib/python2.7/site-packages/ | grep "pyzmq"
pyzmq-14.2.0_dev-py2.7.egg-info
pyzmq_static-2.2-py2.7.egg-info
此外:
which python
/usr/local/bin/python
echo $PYTHONPATH
/usr/local/lib/python:
但是,当我尝试导入时:
Python 2.7.6 (default, Mar 20 2014, 17:55:13)
In [1]: import pyzmq
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-2faa556e5dc0> in <module>()
----> 1 import pyzmq
ImportError: No module named pyzmq
任何帮助我排查问题的建议都非常感谢!
更新:我可以在python中列出zmq模块,但无法列出pyzmq模块:
>>help('modules zmq')
Here is a list of matching modules. Enter any module name to get more help.
buildutils - utilities for building pyzmq.
buildutils.constants - script for generating files that involve repetitive
updates for zmq constants.
buildutils.detect - Detect zmq version
zmq - Python bindings for 0MQ.
...
zmqversion - A simply script to scrape zmq.h for the zeromq version.
IPython.consoleapp - A minimal application base mixin for all ZMQ based
IPython frontends.
IPython.html.base.zmqhandlers - Tornado handlers for WebSocket <-> ZMQ sockets.
...
IPython.utils.zmqrelated - Utilities for checking zmq versions.

我也遇到了安装IPython(Jupyter)的问题,特别是它需要的pyzmq这个依赖。最后,我找到了一种对我来说在Ubuntu上安装的方法,过程简单多了:
$ sudo apt-get install libtool pkg-config build-essential autoconf automake python-dev
$ sudo apt-get build-dep matplotlib
$ sudo pip install matplotlib
$ sudo pip install "ipython[all]"

你需要使用:
import zmq
而不是
import pyzmq
可以查看官方示例,地址是 https://github.com/zeromq/pyzmq/blob/master/examples/
