Example Code

I can't provide a specific example because my codebase is so big/I don't know what is causing the problem. I can provide any relevant snippets if needed. Other apps of mine work fine with the CLI so I'm not sure what's causing the trouble.

Description

• Run fastapi dev/fastapi run
• App starts up temporarily before failing

Here are some examples of failing commands:

Usage
=====
  fastapi [options] [<source> [<destination>]]

fastapi: error: no such option: --root-path

Operating System

Linux

Operating System Details

Ubuntu 22.04 w/ Gnome.

Python Version

Python 3.10.12

Additional Context

The app works fine when using regular uvicorn commands (e.g. python3 -m uvicorn main:app --port 7600).

I'm still not sure what the problem was but uninstalling and remaking my virt env fixed the problem.

[JReeGene]

Running nextjs and fastapi concurrently throws this error:

npm run fastapi-dev exited with code 3221225781

while running them separately resolves the issue, I don't know what happens when I run from my frontend only and fastapi fails to continue.
