python-2.7 - 由于缺少名为 zmq.eventloop 的模块，无法启动 ipython 笔记本

Question

我已经安装了 ipython笔记本最近按照以下说明进行我的机器学习类(class):

步骤 1:创建并激活新的虚拟环境(推荐)

# Create a virtual environment named e.g. dato-env
virtualenv dato-env

# Activate the virtual environment
source dato-env/bin/activate

第 2 步:确保 pip 版本 >= 7

# Make sure pip is up to date
pip install --upgrade pip

第 3 步:确保安装 IPython 和 IPython Notebook

# Install IPython Notebook (optional)
pip install "ipython[notebook]"

一切正常，直到我开始 ipython 笔记本 服务器通过键入以下命令:

ipython notebook

然后弹出以下错误:

我在过去的 Stackoverflow 帖子中尝试了一些方法 here和 here .但似乎他们没有解决我的问题。如果有人可以帮助我解决一些问题并解释实际的问题，我将不胜感激。先感谢您

最好的祝福，
