在 Windows 10 专业版上运行此代码
from flask import Flask
app = Flask(__name__)
@app.route("/")
def index():
return "Hello World!"
if __name__ == "__main__":
app.run(debug=True)
结果如下
** * Serving Flask app "test" (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: on
* Restarting with stat
* Debugger is active!
* Debugger PIN: 198-193-169
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
**
但是当我尝试打开此网址时 http://127.0.0.1:5000/
我在网页上看到以下错误
{"error":"Not found"}
知道为什么这在 Windows 上不起作用吗? 我需要启用任何权限吗?
谢谢

有另一个进程在同一个端口上监听。我杀了那个进程,问题就为我解决了
