Question

ipython notebook 运行时缺少 pyzmq。

32

我可以运行iPython，但是当我尝试启动笔记本时出现以下错误：

~  ipython notebook

ImportError: IPython.html requires pyzmq >= 2.1.11

但据我所见，我已经安装了pyzmq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

对于我（Ubuntu 14.04.2），通过Synaptic软件包管理器安装python3-zmq软件包可以正常工作，该软件包将安装libzmq3。

之后，请检查pyzmq是否正确安装：

pip list

然后我安装了ipython：

pip install "ipython[all]"

对我来说问题在于我安装了 python-zmq 而不是 python3-zmq （ubuntu 16.04）。 - Ott Toomet

使用

ipython2.7 notebook

代替

ipython notebook

这对我起了作用。

注意，ipython的安装过程有些特殊。以下是我解决这个问题所做的步骤：

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

问题在于笔记本电脑有自己的依赖关系，这些依赖关系不会随着pip install ipython一起安装。然而，安装了ipython之后，如果你尝试使用[all]表单，pip就不认为需要添加任何内容。

如评论中所提到的一样，对于一些shell（例如zsh），需要转义或引用方括号（pip install ipython\[all\]也可以工作）。
