Current behavior

Mix.install/1 fails in a new notebook setup when Ecto v3.9.x is a dependency.

To reproduce, create a new notebook and add ecto, either manually or thru package search:

Mix.install([
  {:ecto, "~> 3.9.0"}
])

==> ecto

If this is actually a Livebook problem I will be happy to move this issue over there :)

Expected behavior

Mix.install/1 can install Ecto v3.9.x in a Livebook without error.

Does livebook install an older version of Ecto by default? That looks like an out of date Ecto.Query.Builder module wasn't updated when 3.9.x was installed.

This is a bug in Livebook. We have fixed this in Livebook latest which you can download from the README. :)

[mcrumm]

Fantastic, thanks @josevalim! Next time I'll try that first :)
