使用環境
・Rails 6.0.0
・vagrant
・
問題
下記のようにRailsアプリフォルダに移動し、myappという名のアプリでサーバー起動しようとしたところ、エラーが発生しました。
ここまでは問題なし
$cd
$cd MyVagrant
$cd vagrant ssh
$cd rails_lessons
$cd myapp
このコマンドでエラー発生
$cd rails server -b /*サーバーのIPアドレス*/ -d
こんなエラー
=> Booting Puma
=> Rails 6.0.0 application starting in development
=> Run `rails server --help` for more startup options
RAILS_ENV=development environment is not defined in config/webpacker.yml, falling back to production environment

Please run rails webpacker:install Error: No such file or directory @ rb_sysopen - /home/vagrant/rails_lessons/myapp/config/webpacker.yml (RuntimeError)
可能性の高い原因としては下の三つ。
- Webpacker configuration not found
- No such file or directory @ rb_sysopen
- RuntiimeError
まず1を試す。
対処法としては、
$rails webpacker:installすると、node.jsをインストールしろってコメントが出てくるので、
このサイトを参考にインストールしした。
https://qiita.com/ffggss/items/94f1c4c5d311db2ec71a
そして、再度下のコメントを入れる
$rails webpacker:install
すると今度は、下の表示が出る。
Yarn not installed. Please download and install Yarn from https://yarnpkg.com/lang/en/docs/install/
下のコマンドを打つ。（参照：https://qiita.com/Kumassy/items/116690fdd99dfc91300d）
$ curl -sL https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo $ sudo yum install -y gcc-c++ make yarn git
と、成功。
Webpacker successfully installed 🎉 🍰
そして再度、下のコマンド。
$rails server -b 192.168.33.10 -d
すると、このように返ってきます。
=> Booting Puma
=> Rails 6.0.0 application starting in development
=> Run `rails server --help` for more startup options
本来なら、development以下に、"on IPアドレス"がつくはずです。
このため、rails serverが起動した画面を確認できません。
その理由が不明なので、解消法を探しています。
なお、下のコマンドでバックグラウンドで起動している状態を止めることができたので起動していることは間違いなさそうです。ただ、IPアドレスがわからない。
$cat tmp/pids/server.pid
$kill -9 /*番号*/
