After installing the latest version 1.1.0, it keeps on STARTING!

[iamjinlei0312]

Bug Description

I simply upgraded to the latest version with the command pip install -U langflow, but when I run python -m langflow run, I keep getting the above screen.

Reproduction

To run langflow, I started a separate virtual environment.

python version is 3.11.9.

Hey @iamjinlei0312! 👋 I'm here to help you with any bugs, questions, or contributions. Let's squash this bug together!

I found a similar issue where users experienced problems when running Langflow with the command python -m langflow run. The suggested solution is to use the command langflow run instead, especially if you are on the latest pre-release version. Additionally, it might help to install the latest pre-release in a fresh environment ^[1].

Make sure your Python version is within the required range of >=3.10 and <3.13, which you have already confirmed. If the issue persists, consider checking for any conflicting dependencies in your environment.
