Ale*_*oca 5 python plotly plotly-dash
使用Dash 0.22.0和Python 2.7.12。Plotly 是 3.1.0，但未在以下示例中使用。
我正在尝试创建一个应该完全脱机工作的最小应用程序。
而不是从远程加载的dash_html_components/bundle.js，dash_renderer/bundle.js，react.min.js和react-dom.min.js，我把自己的本地副本在/assets/js。我想告诉 Dash 只使用这些文件的本地副本。
我阅读了资产文件和索引自定义#286，如果我理解得很好，下面的例子应该可以工作：
# -*- coding: utf-8 -*-
import dash
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash()
# default values
app.config.assets_folder = 'assets' # The path to the assets folder.
app.config.include_asset_files = True # Include the files in the asset folder
app.config.assets_external_path = "" # The external prefix if serve_locally == False
app.config.assets_url_path = '/assets' # the local url prefix ie `/assets/*.js`
app.layout = html.Div(
[html.H1("this is a test")]
)
if __name__ == '__main__':
app.run_server(debug=True)

如您所见，我的本地 js 文件是从 加载的/assets，但它不断从 加载相同的文件https://unpkg.com/...
有没有办法避免这种情况？
看起来我错过了一个更简单的解决方案。如果有人试图这样做，我就把它放在这里。
不包括本地副本破折号库（中dash_html_components/bundle.js，dash_renderer/bundle.js，react.min.js和react-dom.min.js中）/assets。
使用/assets仅适用于JS和CSS文件不相关的短跑和反应。就我而言materialize.js，iconjar-map.js以及它们各自的 CSS。
改为添加：
app.css.config.serve_locally = True
app.scripts.config.serve_locally = True
会做的伎俩。
代码现在是：
# -*- coding: utf-8 -*-
import dash
import dash_core_components as dcc
import dash_html_components as html
app = dash.Dash()
# default values
app.css.config.serve_locally = True
app.scripts.config.serve_locally = True
app.config.assets_folder = 'assets' # The path to the assets folder.
app.config.include_asset_files = True # Include the files in the asset folder
app.config.assets_external_path = "" # The external prefix if serve_locally == False
app.config.assets_url_path = '/assets' # the local url prefix ie `/assets/*.js`
app.layout = html.Div(
[ html.H1("This is a test")]
)
if __name__ == '__main__':
app.run_server(debug=True)
以及由此产生的 html：
<!DOCTYPE html>

<head>
<meta charset="UTF-8"/>
