Bootstrap / css / js会在一个模板上加载，但不会在另一个模板上加载-两个模板完全相同。烧瓶

我正在使用jinja2和flask，带有bootstrap / js模板。我有一个base.html，其中index.html，register.html，login.html和my_profile.html都成功地从那里扩展了。

但是，我还有一个channel.html-这也扩展了base.html，但是CSS / JS拒绝在此页面上呈现。即使我将register.html中的HTML粘贴到channel.html中并发送了相同的上下文，该页面仍然拒绝加载其CSS / JS，并且我得到了准系统HTML页面...

如果我从配置文件中删除“扩展自”和“阻止内容”，则页面将呈现-但显然没有CSS / base.html包装页面。如果删除宏，然后仅插入一个简单的<h1>hello</h1>标签，则该页面仍拒绝加载CSS / JS。它似乎挂起，Chrome中显示“正在等待develepment-url.co ...”。

本质上，在此页面上，{％扩展了'base.html'％}导致加载CSS JS加载时出现问题，但它可以在register.html和login.html等上工作。

更新：

我可以看到，该应用正在channel.html上投放

INFO:werkzeug:127.0.0.1 - - [08/Nov/2019 12:11:42] "GET /channel/static/vendor/perfect-scrollbar/perfect-scrollbar.js HTTP/1.1" 404 -

代替

INFO:werkzeug:127.0.0.1 - - [08/Nov/2019 12:11:42] "GET static/vendor/perfect-scrollbar/perfect-scrollbar.js HTTP/1.1" 404 -

但是我不明白为什么。

Routes.py

@app.route('/channel/<username>')
@login_required
def channel(username):
    user = User.query.filter_by(username=username).first()
    return render_template('channel.html',user=user)

Channel.html -不呈现

{% extends "base.html" %}
{% block content %}
{% from 'signal_table.html' import signal_table with context %}
  <div class="page-content--bgf7">
    <section class="p-t-2>
    <h2>{{ user.username }} <a href="{{ url_for('follow',username=user.username) }}" role="button" class="btn btn-sm btn-outline-success">Follow</a>
        </h2>
    {{signal_table(user)}}
    </secdion>
    </div>
{% endblock %}

login.html -确实呈现
