运行ipython笔记本时pyzmq丢失

我可以运行iPython，但当我尝试启动笔记本时，会出现以下错误：

~  ipython notebook

Arg。ipython的安装有点特殊。以下是我必须做的来解决这个问题：

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

问题是笔记本电脑有自己的一组依赖项，它们不是随

pip install ipython

安装的。但是，在安装了ipython之后，如果您尝试使用

[all]

表单，pip认为没有必要添加任何内容

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\[all\]

也可以使用）。

对于我（Ubuntu 14.04.2），synaptic软件包管理器的工作安装：该软件包被称为python3 zmq，该软件包将在libzmq3中安装

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

而不是

ipython notebook

---

为我做了这个把戏。

这对我很有效，但我也必须先卸载pyzmq，否则问题仍然存在。这对我来说也失败了。需要

pip使用zsh安装“ipython[all]”

；其他人则不然。基本上，如果shell要求转义“[]”字符，那么应该将其放在引号中。另外，总是引用它也不会有什么坏处，所以为了更新文档，这个答案可能是值得的：）

pip安装“ipython[notebook]”

不是更好吗？为我解决了同样的问题！！对我来说，这个问题的答案是：我安装了PythonZMQ而不是Python3ZMQ（ubuntu 16.04）

ipython2.7 notebook

ipython notebook
