Simple Instructions to Update an Existing LangFlow Installation

[richlysakowski]

I looked for a command in the main documentation to update langflow, but could not find it. I did not really want to reinstall it again from scratch because it took a very long time, and installed 100s of packages. I have two prior conda environments with langflow installed already, one of which is definitely corrupted because it was from 2 years ago and was not updated ever.

I tried "pip install -qU langflow" to do a silent update ("q" option for "quiet, U for Update). That did not seem like the correct command, so I terminated it.

Finally I found the command Run 'pip install Langflow -U' to update. embedded in the langflow CLI splash screen.

So I just decided to run "langflow" and see what would happen. There I saw the langflow run command.

To my pleasant surprise the langflow run command has embedded "update" instructions that told me what to do.

>> langflow run

Starting Langflow v1.0.18...

There is also "langflow --version" to tell you what version is currently installed.

langflow --version

It would be nice to have a cheatsheet for all the important commands to setup, administer, and maintain LangFlow.
