Ipython 筆記本和 Pyzmq（加上 Jupyter）的問題

我在安裝 Ipython 時遇到了麻煩，但幸運的是我嘗試了 3.2.1 版本，一切正常，我可以運行 Ipython，但我仍然無法運行 Ipython Notebook。

$ 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

我嘗試安裝 pyzmq 並收到以下錯誤：

$ 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

我只複製了錯誤，因為 shell 執行了數百行。

資訊：Python版本2.7.9
我有Anaconda，（不知道它是否改變了什麼）Ubuntu 15.04我安裝了Canopy（Python IDE）（不知道它是否改變了什麼）

編輯：我正在嘗試其他一些東西，然後我決定嘗試安裝 jupyter。我注意到，即使在全新安裝（使用 pip）之後，我也無法運行 jupyter。

$ jupyter notebook
jupyter : command not found.

但現在我可以運行：

~$ 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

[I 00:33:30.386 NotebookApp] The IPython Notebook is running at: http://localhost:8888/
[I 00:33:30.386 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

^C[I 00:37:24.548 NotebookApp] interrupted
Serving notebooks from local directory: /home/renanpc
0 active kernels 
The IPython Notebook is running at: http://localhost:8888/

並且筆記本運作得很好。我對這種情況感到非常非常困惑。

我也遇到了同樣的問題你應該嘗試以下操作：which ipython - 在我的例子中我得到 - "/opt/local/bin/ipython" 然後 ls -l /opt/local/bin/ipython 這會顯示您所在的連結指向「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/ " 現在ls /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/ - 如果您在輸出中看到jupyter - 只需執行以下操作： ln -s /opt/local/Library/Frameworks/ Python。
