Got unexpected extra argument (run)

[kha84]

Bug Description

Installed langflow as explained in document - https://docs.langflow.org/getting-started-installation with the only difference of creating conda env, as I didn't want it to install PIP packages directly to my system:

conda create -n langflow python=3.10
conda activate langflow
python -m pip install langflow -U
python -m langflow run

Upon running the last command I see this:

(langflow) user@magicbook14:~/Projects/Langflow$ python -m langflow run
Usage: python -m langflow [OPTIONS]
Try 'python -m langflow --help' for help.

Hello @kha84! I'm here to help you with any bugs, questions, or contributions you have for Langflow. Let's squash those bugs together!

The error you're encountering, "Got unexpected extra argument (run)," suggests that the command syntax for running Langflow has changed. In recent versions, Langflow is run using the CLI command langflow run [OPTIONS] instead of python -m langflow run ^[1].

To resolve this issue, try running Langflow with the following command:

langflow run --host 0.0.0.0 --port 7860 --log-level info --workers -1 --backend-only

This should start Langflow on your local machine. If you continue to experience issues, ensure that Langflow is correctly installed in your conda environment and that there are no version conflicts.

To continue talking to Dosu, mention @dosu.

Thanks, @dosu but that ain't helping. I have a gut feeling the version I'm getting is way too old (0.0.78) and just does not support the "run" command. Bit strange, I got it, instead of the latest available version as per pypi which is 1.0.19 as per now

[dosubot]

It seems like you're right about the version issue. The run command is not supported in Langflow version 0.0.78. To resolve this, you should upgrade Langflow to the latest version. You can do this by running the following command:

pip install langflow -U

If you want to include pre-release versions, you can use:

pip install langflow -U --pre

After upgrading, try running Langflow again with the updated command:

langflow run --host 0.0.0.0 --port 7860

This should work with the latest version of Langflow ^[1].

nopes, looks like there's some kind of pip incompatibility hell is happening:

What I did is - I dropped the messed-up conda environment:

conda deactivate
conda-env remove -n langflow

then recreated it from scratch, installing the latest available version of langflow and it worked straight away:

conda create -n langflow python=3.10
conda activate langflow
python -m pip install langflow --pre -U
python -m langflow run

Though I still see some minor issues upon startup (actually several hundreds lines of some sort of debug with some warnings and errors), but the web UI at least starting
