flask - 2021-02-16 10:43:57,123 应用程序中的错误：/ GET 异常？

Question

我想在烧瓶应用程序中嵌入/放置一个 tkinter gui，但是我制作的代码似乎没有呈现/显示，并且在我运行我的代码时给出了这个错误：

当我想运行它显示的烧瓶网络服务器时Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

from flask import Flask
from webbrowser import open

app = Flask(__name__)
root = Tk()
root.title("Tkinter")

@app.route('/')
def my_app():
    def click():
        l = Label(root, text = "You Clicked!").pack()
        

    b = Button(root, text = "Click Me!", command = click).pack()
        
    return(root)


if __name__ == '__main__':
    open('http://127.0.0.1:5000/')
    app.run()
    #root.mainloop()
