——文件结构

initpy

from flask import Flask
app = Flask(__name__)
from app import routes

routes.py

from app import app
@app.route('/')
@app.route('/index')
def index():
return "Hello, World!"

microblog.py

from app import app

python变量确实设置为venv one image

Python 3.9.5 Flask 2.0.1 Werkzeug 2.0.1

任何帮助将是伟大的!我已尽力严格按照指南操作。

Answer 1

根据你的文件结构，python是而不是知道microblog.py存在． 这是因为，当您输入from app import app时，python将查找包app

现在，您的microblog.py是不是包的一部分。app。所以，试着把它移动到app文件夹(更准确地说是一个包，因为任何有init的文件夹都被称为包)

修复了，这是一个错别字，它只是在init.py文件名中的一个错别字。

不能关闭，所以当它关闭
