<ol>
|

<li>You've installed Langflow using <code>pip install langflow</code> but you already had a previous version of Langflow installed in your system.

If that doesn't work, try uninstalling and reinstalling Langflow with <code>uv pip install langflow --pre -U</code>.</li>
|

<li>Some version conflicts might have occurred during the installation process. Run <code>python -m pip install langflow --pre -U --force-reinstall</code> to reinstall Langflow and its dependencies.</li>
