To install FastAPI properly, follow these steps:

1. Open your command line interface (e.g. Terminal on Mac, Command Prompt on Windows).
2. Create a new virtual environment by running the following command:

1

python -m venv myenv

Replace "myenv" with the name you want to give to your virtual environment.

1. Activate the virtual environment by running the following command:

• On Windows:

1

myenvScriptsactivate

• On Mac or Linux:

1

source myenv/bin/activate

1. Install FastAPI using pip (which comes with Python) by running the following command:

1

pip install fastapi

1. You may also want to install an ASGI server such as Uvicorn to run your FastAPI application. You can do this by running the following command:

1

pip install uvicorn

1. You can now create and run your FastAPI application. Create a Python file, for example, main.py, and add your FastAPI code.
2. To run your FastAPI application using Uvicorn, run the following command:

1

uvicorn main:app --reload

Replace main with the name of your Python file and app with the name of your FastAPI application instance.

Your FastAPI application should now be up and running. You can access it by navigating to http://127.0.0.1:8000 in your web browser.
