让它在我的本地机器上运行没有问题，但是当部署到 Heroku 时，flask-bootstrap 资产不会导入位于虚拟环境中的 base.html 文件。而且我在日志或控制台中找不到任何错误。

我还需要激活 Heroku 上的虚拟环境还是应该已经处理好？

这是我尝试导入 bootsrap 的 config.py 文件：

from flask import Flask
from flask_bootstrap import Bootstrap
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
Bootstrap(app)
db = SQLAlchemy(app)

app.config['SQLALCHEMY_DATABASE_URI'] = 'URI-is-changed-on-this-question-for-privacy-reasons'

app.config['SECRET_KEY'] = 'secret-key-is-changed-on-this-website-for-privacy reasons'

app.py 导入文件并激活服务器

from config import app
from flask import Flask
from models import authentication, posts
from views import authentication, posts
from forms import authentication, posts

if __name__ == '__main__':
    app.run()

这是尝试扩展 boostrap base.html 的 html 文件

{% extends "bootstrap/base.html" %}
{% import "bootstrap/wtf.html" as wtf %}

{% block jumbotron %}
    <div class="jumbotron">
        <h2>Hunter Krieger</h2>
        <h3>Blogger, Web Developer, Gamer and Bibliophile
    </div>
{% endblock jumbotron %}

{% block content %}
    {% if post %}
        {% for display in post %}
            <article class="well">
                <h1><a href="/{{ display.slug }}">{{ display.title }}</a></h1>
                <h4>Written by {{ display.author }}</h4>
                <h4>{{ display.created_at.strftime('%b %d, %Y') }}</h4>
                <div class="body">
                    {{ display.body | truncate(1250) | safe }}
                </div>
            </article>
        {% endfor %}
    {% else %}
        <p>There are no posts</p>
    {% endif %}
{% endblock %}

这是位于虚拟环境中路径“./venv/Lib/site-packages/flask_bootstrap/templates/bootstrap/base.html”的base.html文件

{% block doc -%}

从看到该代码有人知道我可以改变什么来让flask-bootstrap在Heroku上工作吗？

在您的第一个代码段中，Bootstrap(app)应该是bootstrap = Bootstrap(app)：

from flask import Flask
from flask_bootstrap import Bootstrap
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
bootstrap = Bootstrap(app)  # this line
db = SQLAlchemy(app)
