Flask(flask db init): AttributeError: module 'time' has no attribute 'clock'


While following a Flask tutorial I stumbled around this very strange problem! While setting up the Migrate directory , after the first step of setting the flask app using set FLASK_APP=sql1.py, when I ran this command flask db init I got this error:

(first_flask_env) C:\Users\aakash\Desktop\python programs>flask db init

AttributeError: module 'time' has no attribute 'clock'

I’m getting the exact same error while running my .py script also,here’s the script:

from flask import Flask
import os
from flask_sqlalchemy import SQLAlchemy 
from flask_migrate import Migrate

basedir = os.path.abspath(os.path.dirname(__file__))   #Full directory path of the file I'm working with..here, sql1.py

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'data.sqlite')
db = SQLAlchemy(app)

Migrate(app,db) #Here it connect the application "app.py"
                # with the database "db"    
class puppy(db.Model):
    __tablename__ = 'Name Provided by me!!'
    id = db.Column(db.Integer,primary_key = True)
    name = db.Column(db.Text)
    age = db.Column(db.Integer)
    def __init__(self,name,age):
        self.name = name
        self.age = age
    def __repr__(self):
        return f"puppy {self.name} is {self.age} year/s old!"

I looked into every solution I found (here and this)and made sure everything was correct! I ran this command when my environment was activated which had installed every package needed including SQLAlchemy and Flask-Migrate.

I even deleted them (packages) and re-installed their latest versions but still getting the same error!
I’m using Python 3.8.5


You have some dependencies that are too old and incompatible with Python 3.8. At the very least, you should update the mako package:

pip install --upgrade mako
