What worked for me, both under Windows and under MacOSX , is using Anaconda for all Python apps.在Windows和MacOSX下对我有用的是将Anaconda用于所有Python应用程序。 This post also advises to use Anaconda :这篇文章还建议使用Anaconda ：
Python dependency hell: A compromise between virtualenv and global dependencies? Python 依赖地狱：virtualenv 和全局依赖之间的妥协？

These are the steps I took.这些是我采取的步骤。

Install Anaconda :安装蟒蛇：
https://docs.anaconda.com/anaconda/user-guide/getting-started/ https://docs.anaconda.com/anaconda/user-guide/getting-started/
Under Windows , open the Anaconda cmd prompt from the Anaconda Navigator .在Windows 下，从Anaconda Navigator打开Anaconda cmd 提示符。 Under MacOSX , just open the cmd prompt.在MacOSX 下，只需打开 cmd 提示符。
In the cmd prompt, install plotly with this command:在 cmd 提示符下，使用以下命令安装plotly ：
```
 conda install plotly
```
This installs plotly in the Anaconda environment.这在蟒蛇环境plotly安装。
Launch Spyder from the Anaconda Navigator .从Anaconda Navigator启动Spyder 。 Always launch Spyder from the Anaconda Navigator , to make sure you're running the copy of Spyder from the Anaconda environment.始终从Anaconda Navigator启动Spyder ，以确保您正在从Anaconda环境运行Spyder的副本。
In a Python script, load plotly :在 Python 脚本中，加载plotly ：
```
 import plotly as py
```

After that you should be good to go with plotly .在那之后，你应该很好地使用plotly 。
