Python &引用；加载依赖项时出错“；在企业IE和Chrome中使用某些dcc元素时

我在公司安装的InternetExplorer11和Chrome51中收到“错误加载依赖项”的错误消息，但在我自己安装的最新Chrome中没有。此外，如果我打开开发工具，Internet Explorer也可以正常工作

IE控制台提供以下错误消息

HTML1300: Navigation occurred.

当我删除了

dcc.Graph

和

dcc.RangeSlider

时，应用程序运行良好。单独使用

dcc.Graph

或

dcc.RangeSlider

也会产生

“错误加载依赖项”

问题

我尝试了以下方法：

• 将

  'IE=edge'

  添加到烧瓶中的标题
• 使用

  app_vndr.css.config.serve_locally=True

  和

  app_vndr.scripts.config.serve_locally=True

  本地为脚本提供服务，并使用flask函数将

  /static/path:path/

  路由到正确的文件
• 正在加载babel.js的polyfill。不过，Plotly似乎已经在做这件事了，因为我得到了一条

  消息，您只能有一个babel.js的实例

我应该看什么来解决这个问题？我觉得我错过了一些愚蠢的东西，但我不确定该检查或尝试什么。

在plotly论坛上与mod交谈后，以下步骤修复了问题：

• 从

  仪表板核心组件==0.21.0

  升级到

  仪表板核心组件==0.22.1

• 提供有关图形的实际信息

如果没有为

图={…}

填充的字典，问题仍然存在

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go
import pandas as pd
from functools import partial
import datetime as dt

from SupplyChainReportingTool import server, session, blu, cache, CACHE_TIMEOUT
app_tst = dash.Dash(__name__, server=server, url_base_pathname='/ie_test/')
app_tst.css.config.serve_locally = True
app_tst.scripts.config.serve_locally = True

layout = go.Layout(
    yaxis=dict(title='Count',range=[0, 100],fixedrange=True,side='right',zeroline=False,showgrid=False),
    yaxis2=dict(title='percent',range=[0, 1],fixedrange=True,side='left',overlaying='y')
)
data = [go.Scatter(x=[],y=[],name='Data',mode='lines+markers')]

app_tst.layout = html.Div([
    dcc.Graph(
        id='graphtest',
        figure={'data': data, 'layout': layout}
    )
])

有了这个功能，我仍然需要回到

dash核心组件==0.21.0

，看看这是否真的是个问题

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go
import pandas as pd
from functools import partial
import datetime as dt

from SupplyChainReportingTool import server, session, blu, cache, CACHE_TIMEOUT
app_tst = dash.Dash(__name__, server=server, url_base_pathname='/ie_test/')
app_tst.css.config.serve_locally = True
app_tst.scripts.config.serve_locally = True

layout = go.Layout(
    yaxis=dict(title='Count',range=[0, 100],fixedrange=True,side='right',zeroline=False,showgrid=False),
    yaxis2=dict(title='percent',range=[0, 1],fixedrange=True,side='left',overlaying='y')
)
data = [go.Scatter(x=[],y=[],name='Data',mode='lines+markers')]

app_tst.layout = html.Div([
    dcc.Graph(
        id='graphtest',
        figure={'data': data, 'layout': layout}
    )
])
