ruby (css、js など) を使用してテーマを作成しようとしましたが、解決しようとドキュメントを読むのに何時間も費やしたが成功しなかったというエラーが発生しました。
以下は、次のコマンドを実行したときに表示されるエラーです: bundle exec middleman build --verbose

更新 1:
j03wコメントのおかげで、エラーはforms.html.erbのコードのこの部分に実際にあるようです
<li>
<label>Dropdown with search:</label>
<%= select_tag :colors, options: @colorList.shuffle, class: "chzn-select" %>
</li>
<li>
<label>Dropdown menu:</label>
<%= select_tag :colors, options: @colorList.shuffle, class: "uniform" %>
</li>
これは、配列がある私のconfig.rbの一部です：
@release = false
@colorList = ["Aero blue","Air Force blue (RAF)","Air Force blue (USAF)","Air superiority blue","Alabama Crimson","Alice blue","Alizarin crimson","Alloy orange","Almond","Amaranth","Amazon","Amber",
"SAE/ECE Amber (color)","American rose","Amethyst","Android Green","Anti-flash white","Antique brass","Antique bronze","Antique fuchsia "]
さらに詳しい情報が必要な場合は、お気軽にお問い合わせください。
同じ問題またはそのエラーについて何か考えがあれば、どんな助けでも大歓迎です。
前もって感謝します。
