Bug: Docker Build

[fhkong]

Build Docker Failed

When I build the environment for TeXt Theme with docker, I failed to Step 8/10 RUN bundle install. And I want to know how to fix this bug with docker.

Steps to Reproduce

1. Install Docker on my machine. Ubuntu20.04
2. docker run --rm -v "$PWD":/usr/src/app -w /usr/src/app ruby:2.6 bundle install
3. docker-compose -f ./docker/docker-compose.build-image.yml build

When I do step 3, I get into the following trouble.

Step 8/10 : RUN bundle install
