django_plotly_dash 文档说它们现在与 5x > Django > 3.2x 兼容，但是将 Django 升级到 4.2.1 后，我只能使其在本地工作，但在生产中返回我在下面分享的回溯。

我已经尝试将 python 升级到最新且稳定的版本，但没有成功。
我设法在这里找到包装器的东西：https://github.com/GibbsConsulting/django-plotly-dash/blob/master/django_plotly_dash/dash_wrapper.py
_generate_meta_html 似乎是问题所在......但到目前为止不知道如何解决这个问题。
def index(self, *args, **kwargs): # pylint: disable=unused-argument
scripts = self._generate_scripts_html()
css = self._generate_css_dist_html()
config = self._generate_config_html()
metas = self._generate_meta_html()
renderer = self._generate_renderer()
title = getattr(self, 'title', 'Dash')
if self._favicon:
import flask
favicon = '<link rel="icon" type="image/x-icon" href="{}">'.format(
flask.url_for('assets.static', filename=self._favicon))
else:
favicon = ''
_app_entry = '''
<div id="react-entry-point">
<div class="_dash-loading">
Loading...
</div>
</div>
'''
index = self.interpolate_index(
metas=metas, title=title, css=css, config=config,
scripts=scripts, app_entry=_app_entry, favicon=favicon,
renderer=renderer)
return index
我也有类似的问题：

问题是
dash_generate_meta_html>2.10甚至在 django-plotly-dash 项目的
setup.py中提到不支持这样的版本（但在我这边使用包版本管理器并未将其标记为依赖冲突）。
解决方案：
dash>=2.0,<2.10我希望它有帮助:)
