FlaskWebGUI 地址“拒绝连接”+ 缺少“environ”和“start_response”

问：

我有一个基本的烧瓶应用程序：

from flask import Flask
import flaskwebgui

app = Flask(__name__)
gui = flaskwebgui.FlaskUI(app)

@app.route("/")
def hello():
    return "Hello"

if __name__ == "__main__":
    gui.run()

使用代替按预期工作。没有错误，我得到一个 localhost 链接，我可以单击该链接查看该站点。app.run()gui.run()

但是，如果我执行上述示例中所做的操作，则我的输出会得到以下结果：

path to chrome not found
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python3.10/threading.py", line 1016, in _bootstrap_inner
    self.run()
Command: python3 -m webbrowser -n http://127.0.0.1:33951
  File "/usr/lib/python3.10/threading.py", line 953, in run
    self._target(*self._args, **self._kwargs)
TypeError: Flask.__call__() missing 2 required positional arguments: 'environ' and 'start_response'

我设法通过下载 chromium AppImage 并将 FlaskUI 修改为：

gui = flaskwebgui.FlaskUI(app, browser_path="./chrome.AppImage")

现在，这是输出：

ofstuff/b0unce¡t/app.py

一个没有标签的镶边窗口会像我所期望的那样打开，但它找不到地址：127.0.0.1 refused to connect.
