Q:

运行ipython notebook时缺少pyzmq

我可以运行iPython,但是当我尝试启动笔记本时,我得到以下错误:

~  ipython notebook

ImportError: IPython.html requires pyzmq >= 2.1.11

但据我所知,我已经安装了pyzmq软件包。

~ pip install pyzmq            
Requirement already satisfied (use --upgrade to upgrade): pyzmq in /Library/Python/2.7/site-packages/pyzmq-14.3.1-py2.7-macosx-10.6-intel.egg

Arg。 ipython安装有点特殊。 这是我必须做的,以解决这个问题:

$ pip uninstall ipython
$ pip install "ipython[all]"

问题是笔记本有自己的一组依赖项,这些依赖项没有与pip install ipython一起安装。 但是,安装了ipython后,如果您尝试[all]表单,pip看不到需要添加任何内容。

正如在一些shell(例如zsh)的评论中提到的,有必要转义或引用方括号(pip install ipython\[all\]也可以工作)。

对我来说(Ubuntu14.04.2)由synaptic软件包管理器安装:该软件包称为python3-zmq,使用此软件包将安装libzmq3。

之后检查pyzmq是否正确安装:

pip list

然后我安装了ipython:

pip install "ipython[all]"

使用

ipython2.7 notebook

而不是

ipython notebook

为我做的伎俩。
