本人刚开始学习。想把自己做的网页
在搭建flask环境架构时，出现下面的错误，也不明白该如何修改了。
网络我切断了，ipv4的IP调整成了固定的IP了。可是还是不能运行
from flask import Flask
app = Flask(name)
@app.route('/')
def index():
return '欢迎来到这里！'
if name == 'main':
app.run(debug=True)
运行上面的代码，却出现错误，没有出现结果。
出现的错误提示如下：
E:\Py\掺配网页制作\venv\Scripts\python.exe E:/Py/掺配网页制作/app.py
