`docker compose up` fails to properly install jekyll-diagrams

[nicaudinet]

When doing a fresh install of the website and following the "Running the Website Locally" guide, the docker compose up step fails with the following error:

[+] Running 1/0

My temporary fix is to:

• Run docker compose up
• Drop into the container shell with docker exec -it dsai-nlpgithubio-jekyll-1 bash
• Manually install jekyll-diagrams with gem install jekyll-diagrams
• Quit docker compose up with Control-C
• Re-run docker compose up

This seems to work, but it would be nice to fix this somehow, but I don't know where the error is coming from 🤷

I wonder if it has to do with this:

Anyway, Mehrdad suggested to add the '--build' flag to docker compose, and it seems to work on my side:

sudo docker compose up --build
