[Docker] The story that an error occurred in docker-compose up

docker-compose upWhen I did, I got the following error.

web_1     | => Booting Puma
web_1     | => Rails 6.0.3.1 application starting in development 
web_1     | => Run `rails server --help` for more startup options
web_1     | Usage: yarn [options]

web_1     | yarn: error: no such option: --integrity

web_1     |   Please run `yarn install --check-files` to update.

web_1     | to `false` in your webpacker config file (config/webpacker.yml).

web_1     | Exiting
shitsumonwa_web_1 exited with code 1

No change from the above screen. .. .. Please run yarn install --check-files to update. Because there is

yarn install --check-files

And then try `` `docker-compose up``` again, the same error will be displayed.

web_1     | To disable this check, please change `check_yarn_integrity`
web_1     | to `false` in your webpacker config file (config/webpacker.yml).

Since there was the above description, I changed the contents of config / webpacker.yml.

config/webpacker.yml

development:
  <<: *default
  compile: true

  # Verifies that correct packages and versions are installed by inspecting package.json, yarn.lock, and node_modules
  check_yarn_integrity: true

It was above, but I changed it.

config/webpacker.yml

development:
  <<: *default
  compile: true

  # Verifies that correct packages and versions are installed by inspecting package.json, yarn.lock, and node_modules

#Change the following from true to false
  check_yarn_integrity: false

It worked! !! !!

web_1     | => Booting Puma

web_1     | => Run `rails server --help` for more startup options

Docker-compose up is not possible due to yarn (Your Yarn packages are out of date!)
