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，当我在同一文件夹下的cmd中说Ipython notebook时，它不会在浏览器中打开笔记本并出现以下错误 -

Answer 1

简答：

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，我认为。

我在虚拟环境中的虚拟环境中运行iPython笔记本。我认为虚拟盒子位是无关紧要的，但虚拟环境不是。我在虚拟环境中通过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，我可以清楚地看到安装了pyzmq 。 pip freeze和pip install --upgrade pyzmq都显示我有最新的pyzmq版本，它肯定是＆gt; = 2.1.11（pip freeze|grep pyzmq给pyzmq==14.3.1）。

我退出了virtualenvironment并再次检查了pyzmq并发现pyzmq仅在virtualenv中安装了。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而在外面我的虚拟环境修复了一切，现在一切正常。对不起详细的答案。

Answer 2

回溯很清楚：

您必须安装 pyzmq

pyzmq是ipython笔记本的必备条件有关依赖项列表check this

Answer 3

iPython install documentation说：

[...]你可以用pip获得IPy：
pip install ipython
或者，如果您还想获得IPython笔记本的依赖项：
pip install "ipython[notebook]"

Ipython正在命令提示符下工作，但不在浏览器中
