我只是尝试使用pip安装Plotly.我从Anaconda运行python,现在任何时候我尝试运行任何python我得到以下错误,我不知道如何解决它.我在Windows 7 64bit,Python3,4上运行

    PS Z:\> pip

这是Anaconda版本的pip和最新版本的simplejson(安装Plotly时安装)之间的交互.

作为一种解决方法,

del C:\Anaconda3\lib\site-packages\simplejson

这将允许pip和Plotly再次工作.不幸的是,如果你曾经升级Plotly,这个问题会再次发生,所以我们将在Plotly requirements.txt文件中添加一个解决方法,以防止将来发生这种情况.(Plotly实际上只需要在Python 2.6系统上使用simplejson.)
