該当するコマンド
rails new ,rails -v、rails s
試してみたこと
一度gem uninstall msgpackしてからgem install msgpackをしてみましたが変わらずでした。
###【補足】
・ホームディレクトリなどではrails -vコマンドは正常に使えます。
・他のディレクトリにある以前つくったrailsプロジェクトは、以前はrails sで正常にサーバーを立ち上げられていましたが、今回のエラーが起きてからそちらでも同じエラーが起きるようになってしまいました。
そちらのディレクトリのパスは/Users/Umi/ruby_project/hello_appとなっています。
#【解決しました】
解決いたしましたので参考にさせていただいた記事、行ったことを書き記します。
↑こちらの記事を参考にさせていただいたところgemを再インストールしプロジェクトを作り直せばうまくかもしれないということがわかる。
次に
↑gemの再インストール方法はこちら記事を参考にさせていただきました。
※なお、私は既存のプロジェクトは消さずに進めているため新たにrails newはしていません。
###【gemの再インストールと＋αしたこと】
”gem をクリーンにする。”の記事で紹介されている手順どおり進めていき、
% bundle install
まで特に問題なく成功。もう一度rails sを実行すると以下のようなエラーが発生
/Users/Umi/.rbenv/versions/3.0.0/lib/ruby/gems/3.0.0/gems/webpacker-5.3.0/lib/webpacker/configuration.rb:96:in `read': No such file or directory @ rb_sysopen - /Users/Umi/Desktop/ドットインストール専用/ruby練習用/sample_app/config/webpacker.yml (Errno::ENOENT)
おそらくwebpackerないんだけど！？って怒られてる、と思われる。
なのでそのまま下記コマンドでwebpackerをインストール。
% rails webpacker:install
