error: Variable `typing` not found

[ChristophKarlHeck]

Hi guys, I am trying to build the executor_runner of executorch with the current branch (ceb1f1d05ceab420644a3633264f13547dc02411) of https://github.com/pytorch/executorch. Executing the following command:

/tmp/buck2 build //examples/portable/executor_runner:executor_runner --show-output

This leads to the following error:

File changed: root//.buckconfig.swp

What is going wrong here?

Older Buck2 doesn't have support for typing module. Can you try with the latest version? It's been present a while, so I suspect the latest binary on the website would be sufficient

@ndmitchell Thank you, it solved my issue :)
