Question

我正在尝试从Flask quickstart运行一个最小的应用程序。我安装了Flask，设置FLASK_APP并尝试：烧瓶运行

这是应用代码：

from flask import Flask

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello, World!'

这是控制台答案：

E:\app>flask run
 * Serving Flask app "dapp.py"
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: off
Traceback (most recent call last):

    self.server_name = socket.getfqdn(host)

    hostname, aliases, ipaddrs = gethostbyaddr(name)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa3 in position 0: invalid

有什么可以做到的？

Flask无法使用Windows 7
