Answer to the question: https://flask.palletsprojects.com/_/downloads/en/1.1.x/pdf/

Run the app:

set FLASK_APP=newproj
set FLASK_ENV=development
flask run

Firstly you should create virtualenvironment for your flask project in yor desktop.

• install virtualenvironment : install virtualenvironment at your terminal or dos

  pip install virtualenv

• create a new folder for your project (i show you creating folder at terminal)

  mkdir newproj

  cd newproj

  virtualenv venv

• mkdir newproj : created new folder named "newproj"

• cd newproj : change directory to "newproj"

• virtualenv venv : created virtualenvironment named "venv"

and activate your venv.

C:\Users\name\abc> venv\Scripts\activate

Now, you can start install flask.

pip install Flask

If you use pycharm, open your folder in your editor. And create a new python file named hello.py (or another things). Write code below inside ypur python file.

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
   return 'Hello World’

if __name__ == '__main__':
   app.run()

Open pycharm editor and if venv is deactivate, activate venv. The above given Python script is executed from Python shell.

python hello.py

Debug Mode:

# app.run(debug = True)

app.run(host='127.0.0.1',port=8000,debug=True)

Summary :

$ export FLASK_APP=app.py # your python file name$ set FLASK_APP = app.py$ export FLASK_ENV=development$ set FLASK_DEBUG = True$ flask run

Here is a tricky part which I meet currently, for my situation I do download python too but cannot recognised via python --vesrion

try with py --version, it work in my case and use py instead of python for other command too
