How to install fastapi on an offline computer

I am learning python on a computer without internet. I need to install fastapi and uvicorn.
On a computer with internet access, I would just have to type "pip install fastapi" and 'pip install "uvicorn[standard]"'.

But my computer is not connected to the internet.

How do I install fastapi and uvicorn?

Where can I download offline installers? And what to type in pip?

I downloaded fastapi_offline from here https://pypi.org/project/fastapi-offline/#files
But the installation failed.

If you have the option, using pip download is the way to go, since this will also include and transient dependencies (i.e. everything that FastAPI depends on, and everything those packages depends on, etc.). For the current version of FastAPI and uvicorn, this ends up being these packages and versions:

anyio-3.6.2-py3-none-any.whl
click-8.1.3-py3-none-any.whl
colorama-0.4.6-py2.py3-none-any.whl
fastapi-0.92.0-py3-none-any.whl
h11-0.14.0-py3-none-any.whl
idna-3.4-py3-none-any.whl
pydantic-1.10.5-cp310-cp310-win_amd64.whl
sniffio-1.3.0-py3-none-any.whl
starlette-0.25.0-py3-none-any.whl
typing_extensions-4.5.0-py3-none-any.whl
uvicorn-0.20.0-py3-none-any.whl

Since every package has none as its platform, they should all work on both Windows, OS X and Linux.

If you want database libraries (such as SQLAlchemy), the number of required packages will grow a lot.

Even if you can't install anything on the computer where you want to download the packages, if you can get the packages off that computer with a usb drive, you can install python/pip on the USB drive, and then use that pip executable to download the packages for you.

The .whl-files can be installed using pip install <whl file> on your computer without internet access..
