使用Pycharm运行一个非常简单的Bokeh Server示例-无法解码JSON对象 [英] Running a very simple Bokeh Server example using Pycharm - No JSON object could be decoded

问题描述

以下代码是从

The following code is a very simple bokeh server example retrieved from the Specifying output_server section. It works and I get a Bokeh plot on my browser if I run bokeh serve in one terminal and then this code in a desperate python shell

from bokeh.plotting import figure, show, output_server

p = figure(title="Server Plot")
p.circle([1, 2, 3], [4, 5, 6])

output_server("hover")

show(p)

但是，当我尝试从pycharm运行此代码时，会得到以下回溯:

However, when I try to run this code from pycharm I get the following traceback:

推荐答案

哇，好吧，我只是事后尝试了一下，然后就奏效了.将解释器更改为Python 3.4.0

Wow, well I just tried something as an afterthought and it worked. Change the interpreter to Python 3.4.0

在Pycharm中，转到文件"->设置" 转到项目解释器选项卡 从下拉列表中将解释器"更改为3.4.0并应用.

In Pycharm, go to File -> Settings Go to the Project Interpreter tab From the drop-down list change the Interpreter to 3.4.0 and apply.

示例重新运行后，令我惊讶的是

Upon rerunning, much to my surprise, the example works.

我欢迎任何人修改此答案或在下面添加一个答案，以解释这是为什么的原因，因为据文档似乎告诉我，Bokeh支持2.7.

I welcome anyone to modify this answer or add one below that explains why this is because as far as the docs seem to be telling me, 2.7 is supported by Bokeh.
