我是 webpack 的新手，但非常想掌握这项技术。我通过 python 脚本运行 Flask 应用程序__init__.py并在 cmd 中运行 webpack 来开发我的 Web 应用程序npm run start。
完成一些开发后，我执行npm run build并将整个文件夹推.build送到 Ubuntu 服务器。
我的项目具有以下结构：
├── api.log
├── app.py
├── assets
│ ├── images
│ ├── scripts
│ └── styles
├── build
│ ├── manifest.json
│ └── public
├── db.log
├── flask_webpack_test.iml
├── __init__.py
├── node_modules
│ == bunch of them here
├── package.json
├── package-lock.json
├── __pycache__
│ ├── api.cpython-35.pyc
│ ├── app.cpython-35.pyc
│ ├── config.cpython-35.pyc
│ ├── db_connection.cpython-35.pyc
│ ├── __init__.cpython-35.pyc
│ └── our_logging.cpython-35.pyc
├── templates
│ └── index.jinja2
├── tests
│ ├── conftest.py
│ ├── __init__.py
│ └── test_views.py
├── webpack.config.js
└── wsgi.py
但是当我访问我的域名时，它只显示纯 html，没有任何静态内容。在网络浏览器控制台中，我看到Unchecked runtime.lastError: The message port closed before a response was received.
我复制了测试项目这里
因此，连接通过端口 2992 中止。在我的 Ubuntu 服务器上，我打开了它。
我的清单.json

webpack.config.js：

var rootAssetPath = './assets';
module.exports = {

new ManifestRevisionPlugin(path.join('build', 'manifest.json'), {

};
python 文件给出了 html：
from flask import Flask, render_template
from werkzeug.serving import run_simple
from flask_webpack import Webpack
webpack = Webpack()
def create_app(settings_override=None):
"""
Create a test application.
:param settings_override: Override settings
:type settings_override: dict
:return: Flask app
"""
app = Flask(__name__)
params = {
'DEBUG': False,
'WEBPACK_MANIFEST_PATH': './build/manifest.json'
}
app.config.update(params)
# if settings_override:
# app.config.update(settings_override)
webpack.init_app(app)
return app
app = create_app()
@app.route('/')
def index():
return render_template('index.jinja2')
# @app.route('/s')
# def index():
# return render_template('index.jinja2')
if __name__ == '__main__':
app.run(port=5000)
# run_simple('localhost', 5000, app, use_reloader=True, use_debugger=True)
任何人都可以帮忙解决这个问题吗？我的设置有什么问题以及为什么我无法在我的服务器上运行 webpack？
