エラー文詳細
syntax error, unexpected end, expecting end-of-input (SyntaxError)

調べたこと

　endが抜けいることで生じるエラー。

コード

　```ruby

このメソッドを閉じるendがないようです。

このメソッドにendをつけて記述を変更しましたが解決できませんでした。 def self.parse!(argv) options = {} sub_command_parsers = create_sub_command_parsers(options) command_parser = create_command_parser begin command_parser.order!(argv) options[:command] = argv.shift sub_command_parsers[options[:command]].parse!(argv) if %w(update delete).include?(options[:command]) raise ArgumentError, "#{options[:command]} id not foud." if argv.empty? options[:id] = Integer(argv.first) end rescue OptionParser::MissingArgument, OptionParser::InvalidOption, ArgumentError => e abort e.message end end end
