Question

我实际上在笔记本电脑上更改了驱动程序，并安装了python 3.7的最新版本，我安装了python 3.7，并安装了我主要使用的所有flask模块。但是当我运行旧项目时，出现了AttributeError: 'Blueprint' object has no attribute 'teardown_appcontext'错误，我不知道该如何解决，我也试图寻找解决方案，但仍然没有帮助。

更多信息是实际错误：

回溯（最近通话最近）：在第33行的文件“ app.py”中从蓝图导入* 在第7行的文件“ / Users / kim / Documents / Python / WebApp Projects / joannets / blueprints / init .py”中从blueprints.routes.index导入APP_BLUEPRINT_INDEX 文件“ / Users / kim / Documents / Python / WebApp Projects / joannets / blueprints / routes / index.py”，第6行缩小（APP_BLUEPRINT_INDEX） init 中的文件“ /Users/kim/Documents/env/lib/python3.8/site-packages/flask_minify/main.py”，第64行 app和self.init_app（app） init_app中的文件“ /Users/kim/Documents/env/lib/python3.8/site-packages/flask_minify/main.py”，第87行 app.teardown_appcontext（self.teardown） AttributeError：“蓝图”对象没有属性“ teardown_appcontext”

这是主要的app.py：

import os
import yaml
import datetime

from flask         import Flask, render_template
from flask_mysqldb import MySQL
from flaskwebgui   import FlaskUI

APPLICATION = Flask(__name__)

APPLICATION.secret_key = "J0@nNeTrucKinG53rvic3S"

# Get the directory folder name
def directory():
    return os.path.dirname(os.path.abspath(__file__))

# Join the Directory name with the path target
def fileInclude(joinPath):
    return os.path.join(directory(), joinPath)

# Open the yaml database configure file
dbConfig = yaml.load(open(fileInclude("config/dbconfig.yaml")), Loader = yaml.FullLoader)

APPLICATION.config["MYSQL_HOST"]        = dbConfig["DB_HOST"]
APPLICATION.config["MYSQL_DB"]          = dbConfig["DB_DATABASE"]
APPLICATION.config["MYSQL_USER"]        = dbConfig["DB_USERNAME"]
APPLICATION.config["MYSQL_PASSWORD"]    = dbConfig["DB_PASSWORD"]
APPLICATION.config["MYSQL_CURSORCLASS"] = "DictCursor"

_DATABASE_ = MySQL(APPLICATION)

from blueprints import *

"""
    It will handle the URL error 
    if the request of page not found.
"""
@APPLICATION.errorhandler(404)
def PAGE_NOT_FOUND(error):
    return render_template("/404/index.html")

"""
    This injection function will help
    to create a local variable to use in templates.
"""
@APPLICATION.context_processor
def INJECT_SUB_HELPERS():
    return {"COMPANY": "", 
            "DATEYEAR": datetime.datetime.now().strftime("%Y")}

if __name__ == "__main__":
    # INTEND TO USE THIS FRO PRODUCTION
    UI = FlaskUI(APPLICATION)
    UI.run()

    # FOR DEBUGGING
    # APPLICATION.run(debug = True)

这是我存储了所有蓝图模块的蓝图文件：

"""
    Register all blueprints frame / routes here
"""

from app import APPLICATION

from blueprints.routes.index    import APP_BLUEPRINT_INDEX
from blueprints.routes.login    import APP_BLUEPRINT_LOGIN
from blueprints.routes.vehicles import APP_BLUEPRINT_VEHICLE
from blueprints.routes.drivers  import APP_BLUEPRINT_DRIVERS
from blueprints.routes.twogo    import APP_BLUEPRINT_2GO
from blueprints.routes.tanduay  import APP_BLUEPRINT_TANDUAY
from blueprints.routes.laplap   import APP_BLUEPRINT_LAPLAP


APPLICATION.register_blueprint(APP_BLUEPRINT_LOGIN)
APPLICATION.register_blueprint(APP_BLUEPRINT_INDEX)
APPLICATION.register_blueprint(APP_BLUEPRINT_VEHICLE)
APPLICATION.register_blueprint(APP_BLUEPRINT_DRIVERS)

AttributeError：“ Blueprint”对象在python3.8上没有属性“ teardown_appcontext”
