$ docker-compose run web rails new . --force --database=mysqlで新規Railsプロジェクトが作成できずにいます。
以下のようにRailsは5.1.6、i18nは1.0.1が入っている状態です。
$ rails -v Rails 5.1.6
$ gem uninstall i18n You have requested to uninstall the gem: i18n-1.0.1 activesupport-5.2.4.1 depends on i18n (< 2, >= 0.7) activesupport-5.1.6 depends on i18n (< 2, >= 0.7) If you remove this gem, these dependencies will not be met. Continue with Uninstall? [yN] N
$ docker-compose run web rails new . --force --database=mysqlを実行します。

Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine. The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`. Fetching gem metadata from https://rubygems.org/............

Use `bundle info [gemname]` to see where a bundled gem is installed. Post-install message from i18n: HEADS UP! i18n 1.1 changed fallbacks to exclude default locale. But that may break your application. If you are upgrading your Rails application from an older version of Rails: Please check your Rails app for 'config.i18n.fallbacks = true'. If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be 'config.i18n.fallbacks = [I18n.default_locale]'. If not, fallbacks will be broken in your app by I18n 1.1.x. If you are starting a NEW Rails application, you can ignore this notice. For more info see: https://github.com/svenfuchs/i18n/releases/tag/v1.1.0 Post-install message from sass: Ruby Sass has reached end-of-life and should no longer be used. * If you use Sass as a command-line tool, we recommend using Dart Sass, the new primary implementation: https://sass-lang.com/install * If you use Sass as a plug-in for a Ruby web framework, we recommend using the sassc gem: https://github.com/sass/sassc-ruby#readme * For more details, please refer to the Sass blog: https://sass-lang.com/blog/posts/7828841 run bundle exec spring binstub --all * bin/rake: Spring inserted * bin/rails: Spring inserted
「i18n 1.1でデフォルトロケールを除外するようにフォールバックを変更しました、 I18n (>= 1.1.0) か Rails (< 5.2.2) でこの症状が出る」と表示されます。
実行後にRailsとi18nのバージョンを見ても、i18nは1.0.1でRailsは5.1.6なのでこのエラーは回避できそうな気がします。
しかし以下のようにdbは作成されてますがwebは作成されていません。
$ ls docker-compose.yml Dockerfile Gemfile Gemfile.lock $ docker-compose ps The system cannot find the path specified. Name Command State Ports ----------------------------------------------------------------------- rails0_db_1 docker-entrypoint.sh mysqld Up 3306/tcp, 33060/tcp
これはどのように解決すればいいでしょうか？
参考のためファイルの中身を貼っておきます。
