Question

我是烧瓶新手从烧瓶进口烧瓶 app = Flask(名称)

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

@app.route("/Aj")
def helloAj():
    return "Hello AJ!"
if __name__=="__main__":
     app.run(port=5000)

这给了我正确的输出，但是当我写 app.run(debug=True)

from flask import Flask
app = Flask(__name__)

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

@app.route("/Aj")
def helloAj():
    return "Hello AJ!"
if __name__=="__main__":
     app.run(debug=True)

它给了我错误，如下输出

* Serving Flask app "__main__" (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 windowsapi reloader
An exception has occurred, use %tb to see the full traceback.

SystemExit: 1

下面是%tb命令的输出

在 app.run 中使用 debug = True 时出错
