Ipython 笔记本和 Pyzmq (以及 Jupyter) 的问题

我在安装 Ipython 时遇到了麻烦，幸好我尝试了 3.2.1 版本，一切正常，我可以运行 Ipython，但我仍然无法运行 Ipython 笔记本。

$ ipython

Python 2.7.9 (default, Apr  2 2015, 15:33:21) 
Type "copyright", "credits" or "license" for more information.

IPython 3.2.1 -- An enhanced Interactive Python.


$ ipython notebook
...
ImportError: IPython.html requires pyzmq >= 13

我尝试安装 pyzmq 但出现以下错误：

$ sudo pip install -U pyzmq
...
Warning: Failed to build or run libzmq detection test.



If you expected pyzmq to link against an installed libzmq, please check to make sure:



    * You have a C compiler installed

    * A development version of Python is installed (including headers)

    * A development version of ZMQ >= 2.1.4 is installed (including headers)

    * If ZMQ is not in a default location, supply the argument --zmq=<path>

    * If you did recently install ZMQ to a default location,

      try rebuilding the ld cache with `sudo ldconfig`



      or specify zmq's location with `--zmq=/usr/local`
       ...
          compilation terminated.

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

我只复制了错误，因为 shell 执行了数百行代码。

信息：Python 版本 2.7.9
我有 Anaconda，（不知道它是否会改变任何东西）Ubuntu 15.04 我有 Canopy（Python IDE）（不知道它是否会改变任何东西）

编辑：我尝试了一些其他的东西，然后决定尝试安装 jupyter。我注意到，即使在全新安装（使用 pip）后，我也无法运行 jupyter。

$ jupyter notebook
jupyter : command not found.

但现在我可以运行：

~$ ipython notebook
[I 00:33:30.336 NotebookApp] Writing notebook server cookie secret to /run/user/1000/jupyter/notebook_cookie_secret
[I 00:33:30.386 NotebookApp] Serving notebooks from local directory: /home/renanpc

^C[I 00:37:24.548 NotebookApp] interrupted
Serving notebooks from local directory: /home/renanpc

The IPython Notebook is running at: http://localhost:8888/

笔记本运行正常。我对这种情况非常困惑。

我遇到过同样的问题您应该尝试以下操作：哪个 ipython - 在我的情况下我得到 - “/opt/local/bin/ipython”然后 ls -l /opt/local/bin/ipython 这将向您显示链接指向的位置“lrwxr-xr-x 1 root admin 71B 11 фев 17:49 /opt/local/bin/ipython@ -> /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/ipython”现在 ls /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/ - 如果您在输出中看到 jupyter - 只需执行以下操作：ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/jupyter /opt/local/bin/
