Error when deploying the site locally

[MartinDelille]

I just updated my local repository and I have a problem when starting the site locally:

It looks like I have a dependency problem. Any idea to fix that?

[mattbk]

Yeah, you need to install that module. This was added in bd830c9#diff-ba951dcdfc393700974a4eb3449bdb50.

[MartinDelille]

How?

[mattbk]

Did you rebuild the Docker container since that commit?

# build the local container
docker-compose build

I would guess that is where the dependencies are installed.

[MartinDelille]

No and it fixed the problem. Thanks again @mattbk !
