python - 每次我尝试运行破折号应用程序时出现回溯错误

问题描述

我是 dash 的新手，我完成了 dash、dash-core-components、dash-html-components 的初始安装。

但是每次我运行这个或任何其他与破折号相关的代码时，我都会收到多个回溯错误。请提出解决此问题的方法。谢谢 ：）

import dash
import dash_core_components as dcc
import dash_html_components as html

app=dash.Dash()

app.layout=html.Div(children=[
html.H1('Server Uptime'),
dcc.Graph(id='Uptime',
          figure={'data':[
              {'x':[1,2,3], 'y':[5,4,7], 'type':'bar','name':'Serverstuff'}],
              'layout':{'title':'Basic Example'
              }
          })
])
if __name__=='__main__':
    app.run_server(debug=True)

错误：
