Deploy Streamlit app in Streamlit Community Cloud

I have tried to deploy a streamlit app on Streamlit Community Cloud. I followed the instructions given here. But as I write code in GitHub Codespace, the new written codes are not saved to the git repository, even after save it. Also, when I open my streamlit app link from my Streamlit Community Cloud, I found it opens a welcome page instead of my streamlit app.

Hi! From the color highlighting, it looks like you did not commit and push your changes from your codespace to your Git repository. This article might be of use Using source control in your codespace - GitHub Docs .

If that doesn’t work, we can jump on a call and go through the process together. Maybe we can find ways to improve editing in codespaces :slight_smile:

Could you enter a commit message in the top left and then press the commit button? The commit is still not complete

      pg_config is required to build psycopg2 from source.  Please add the directory

      containing pg_config to the $PATH or specify the full executable path with the

      option:

Hey @Sanniddha ! This appears to be an issue with one of your dependencies. Can you share access to your source code? If not, can you create a smaller application that reproduces the issue?

@Alexandru_Toader

This is my code repo

Ignore Fly.toml and Dockers files.

Thank you! We’ll look into it and see if this is an issue on our side.

Hi @Sanniddha, this is a know issue with psycopg2. You have two options:

  • Install psycopg2-binary instead of psycopg2 - simple, fast and recommended - which is a binary distribution
  • Install the libraries and sources required by psycopg2 - a bit harder - you can do so using APT
