アプリ フォルダーにいますが、コマンドrails s
が機能しません。Stack Overflow に関するかなりの数の投稿を読みましたが、それらのほとんどは、アプリ ディレクトリにないユーザーからのもののようです。
さらに、いくつかのアプリを作成しました。それらを確認したところ、Rails サーバーはこれらすべてのアプリで動作します。これは、起動できない唯一のものです。

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
私は Hartl の Rails チュートリアルに取り組んでおり、彼は gemfile にかなりの変更を加えています。これが原因なのかな?と思います。
