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

推荐答案

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

This is an interaction between Anaconda's version of pip and the latest version of simplejson (which was installed when you installed Plotly).

作为一种解决方法，

del C:Anaconda3libsite-packagessimplejson

这将允许 pip 和 Plotly 再次工作.不幸的是，如果你升级 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.(在 Python 2.6 系统上实际上只需要 simplejson.)

This will allow pip and Plotly to work again. Unfortunately if you ever upgrade Plotly this problem will happen again, so we will add a workaround to the Plotly requirements.txt file that prevents this from happening in future. (Plotly only actually needs simplejson on Python 2.6 systems.)
