在Windows上运行Flask应用程序会引发“尝试在不是套接字的东西上的操作” [英] Running Flask app on Windows raises "an operation was attempted on something that is not a socket"

问题描述

当运行一个基本的Flask应用程序时，我在shell中发现了这个错误，并且找不到如何解决这个问题。

  from flask import Flask，render_template 
 $ b app = Flask（__ name__）
 
 @ app.route '/'）
 def main（）：
 return render_template（'main.html'）
 
 app.run（debug = True）
  
 
 
  app.run = False）
  
同时我也在寻找一种方法来在Windows上实际使用调试模式。 / p>

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def main():
    return render_template('main.html')

app.run(debug=True)

解决方案
i know it is not a solution to the core problem, but for me the issue only occurs when setting the debug flag to True. If you can use your app without the debug/reloading features you might want to give it a try:
app.run(debug=False)
Meanwhile i am too searching for a way to actually use the debug mode on windows.
