• [ ] I'd be willing to implement a fix

Describe the bug

I am upgrading Yarn to v2 on a containerized app but when running the yarn install command in an entrypoint script it fails with the following error:

app_1  | (node:92) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise ➤ YN0001: RangeError: Invalid count value

This is the relevant part of the docker-compose file:

app: build: context: . target: dev image: ### command: puma -C config/puma.rb entrypoint: - yarn.sh

Interestingly enough, when I exec into the pod, I am able to run yarn install successfully. It only fails when running docker-compose up

Screenshots

Environment if relevant (please complete the following information):

• OS: Linux
• Node version: 12.16.1
• Yarn version: 2.0.0-rc.34

I have the same problem as soon as I add tty: true in my docker-compose to have colored logs.
