Ipython正在命令提示符下工作,但不在浏览器中

Question

我使用的是Windows 8 64位笔记本电脑.我已经在我的电脑上安装了python 2.7.所以我使用easy_install安装了Ipython.我现在可以在C:\ Python27\Scripts中看到一个ipython应用程序文件.当我运行该文件时,它会打开我的cmd,我可以编写代码.但是,当我Ipython notebook在同一文件夹下的cmd中说它没有在浏览器中打开笔记本并给出以下错误 -

Answer 1

简短回答:

确保pyzmq安装在与ipython相同的虚拟环境中(或缺少).对我来说,ipython笔记本是按常规安装的,但它的依赖关系已经放入了我的虚拟环境中.在适当的地方快速安装为我修复了这个错误.

答案很长:

我在这里提出这个解决方案,因为错误信息是相同的,尽管场景与原始海报不同,我想.

我在虚拟盒子上的虚拟环境中运行iPython笔记本.我认为虚拟盒位是无关紧要的,但虚拟环境不是.我在virtualenvironment中通过pip安装了ipython [notebook]并得到了同样的错误ImportError: IPython.html requires pyzmq >= 2.1.11

但是,我可以清楚地看到pyzmq 已经安装好了.双方pip freeze并pip install --upgrade pyzmq表明我有可用的最新版本pyzmq,它肯定是> = 2.1.11(pip freeze|grep pyzmq给pyzmq==14.3.1).

我退出了虚拟环境,并再次检查pyzmq,发现pyzmq安装只在virtualenv中.这应该是它应该工作的方式,但由于某种原因,ipython正在寻找主要的python位置,而不是virtualenv的python位置.我怀疑ipython是在虚拟环境之外安装的.我不知道为什么pyzmq只在其中安装.无论如何,pip install pyzmq虽然在我的虚拟环境之外修复了一切,现在一切正常.对不起详细的回答.

Answer 2

追溯很明确:

你必须安装pyzmq

pyzmq是ipython笔记本的必备条件.
