Question

当我运行以下python脚本时

from flask import Flask
app = Flask(__name__)

@app.route('/')
def index():
    return 'Hello_World'

控制台输出以下内容：

* Serving Flask app "main.py"
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 14: invalid continuation byte

操作系统：Windows 10 Python版本：3.8.5 烧瓶版本1.1.2

我通过cmd打开了一个venv，然后安装了flask，并尝试运行带有上述错误的脚本。

运行烧瓶脚本会出现UnicodeDecodeError错误
