Prerequisite
As mentioned, this is an application written in Python. Consequently, it is essential to have this language installed. To know how to do it, see our tutorial.
How to download and install Flask in Windows 10. Step by step.
In the first place, it is necessary to create a folder where you will save the configuration of the app. With this in mind, we will create it inside Documents and call it my_flask.
Then open a CMD as an administrator from the folder location and run the following command:
py -m venv env
With this command we have created the virtual environment of Flask. In effect, all you have to do is go to the folder and look at the content.
Back to the terminal, please run the following command to activate the environment:
env\Scripts\activate
Now, install Flask with the following command:
pip install flask
Once Flask is downloaded and installed, the wizard recommends updating the pip. With this in mind, run the following command:
python.exe -m pip install --upgrade pip
Creating the configuration file.
Now it’s time to create an app.py file. Consequently, some advanced text editor like Notepad++ is recommended. Finally, save it in the newly created folder.
Then, please establish the application with the following order:
set FLASK_APP=app.py
Then open the app.py file and add the following lines:
from flask import Flask
app = Flask(name)
@app.route('/')
def index():
return '<h1>Hello</h1>'
To run this environment go to the terminal and there run:
flask run
Then, select the assigned IP address in the terminal. Then open it in any browser.
Ultimately we have seen how you install Flask on Windows 10. Besides, it is written in python so it has a great support. See you later!
