GitHubでリポジトリつくる
localにcloneしてくる
$ git clone https://github.com/k-tetsuhiro/rails_docker_sample_3.git
& cd rails_docker_sample_3
bundleを初期化する
$ bundle init
Writing new Gemfile to /Users/kakuno/sandbox/rails_docker_sample_3/Gemfile
Gemfileができているので編集する
$ vi Gemfile
Gemfile
# frozen_string_literal: true
source "https://rubygems.org"
git_source(:github) {|repo_name| "https://github.com/#{repo_name}" }
gem "rails"
→ # gem "rails" のコメントアウトをはずす
bundle installして必要なものをインストールする
$ bundle install --path vendor/bundle
[DEPRECATED] The `--path` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set path 'vendor/bundle'`, and stop using this flag

create .gitignore
conflict Gemfile
Overwrite /Users/kakuno/sandbox/rails_docker_sample_3/Gemfile? (enter "h" for help) [Ynaqdhm]
--- ここで上書きしていいか聞かれるのでYを押して許可する ---
→最後になにかエラーメッセージが出てたらもう一度bundle installする
$ bundle install --path vendor/bundle
webpackerをinstallする
$ rails webpacker:install
create config/webpacker.yml
Copying webpack core config
create config/webpack
create config/webpack/development.js
--- 必要なものが入っていく ---
Railsサーバーを起動してみる
$ bundle exec rails s
→ようやくRails起動!! http://localhost:3000/

$ vi .gitignore
→無視するファイルを設定
