Plotly 杀死了我的 python 安装

I just tried to install Plotly using pip. I am running python from Anaconda and now anytime I attempt to run anything python I get the following errors and I have no idea how to fix it. I am running on Windows 7 64bit, Python3,4

    PS Z:> pip

解决方案

这是Anaconda的pip版本和最新版simplejson(安装Plotly时安装的)的交互.
