我已经构建了一个单页dash应用程序,当作为单个文件运行时,它会按预期运行,但当我尝试将其作为一个整体应用程序运行时,CSS无法正确加载

下面是我的文件夹结构

当我通过
manage.py加载整个应用程序时,下面是我得到的错误

Internal Server Error: /assets/internal.css

这是我唯一的第二个dash应用程序,我正在工作,不幸的是没有太多的经验。如果有人能帮我解决这个问题,我真的很高兴。我已经挣扎了几天了


提前多谢

通过不断的研究,我通过在server.py中添加以下内容解决了这个问题

css_directory = os.getcwd()
stylesheets = ['stylesheet.css']
static_css_route = '/static/'


@app.server.route('{}<stylesheet>'.format(static_css_route))
def serve_stylesheet(stylesheet):
    if stylesheet not in stylesheets:
        raise Exception(
            '"{}" is excluded from the allowed static files'.format(
                stylesheet
            )
        )
    return flask.send_from_directory(css_directory, stylesheet)


for stylesheet in stylesheets:
    app.css.append_css({"external_url": "/static/{}".format(stylesheet)})
css_directory=os.getcwd() 样式表=['stylesheet.css'] 静态路径='/static/' @app.server.route({}.format(static_css_route)) def SERVER_样式表(样式表): 如果样式表不在样式表中: 引发异常( “{}”已从允许的静态文件中排除。格式( 样式表 ) ) 返回flask.send_from_目录(css_目录,样式表) 对于样式表中的样式表: append_css({“外部url”:“/static/{}.format(样式表)})
