Issue: Web failed to build

Docker Desktop
1

Hello everybody, I’m new on docker and I’m working on a project that started before I get in. So my problem is with docker-compose build and docker-compose up -d Cuz I’m trying to run the project for the first time in Windows and I don’t know what I missing around.

When I try to run the docker-compose build this is what I get:

C:\Users\alien\Documents\workspaces\ambit\ambit-pac-gateway>docker-compose build
