とりあえず、Rails 5.2.3 環境を作って動作確認まで。
Rails 5.2.3 環境のインストールと動作確認
gem の設定
bundle で gem をインストールする際に、ドキュメントをインストールすると遅くなったり容量を喰ったりであまりよろしくないので、bundle install の際にドキュメントをインストールしないように設定
$HOME/.gemrc

install: --no-document update: --no-document |

必要な Gem のインストール
Gemfile に devise とか bootstrap とか追加。あとから使うので fonts-awesome-sass も追加しておく。
ActiveStorage もちょっとよくわからないので、一旦使いなれた CarrierWave を使う方向で。

インストールの確認
webrick を使ってインストールの確認を実施

$ bundle exec rails s -b 0.0.0.0 |
いつもの画面が表示されればOK.
