這裏是一個相當新的rails開發人員。我試圖在Heroku上有效地部署我的rails應用程序時遇到了此錯誤消息。我的猜測是JS資源預編譯時會遇到一些語法錯誤。ExecJS :: RuntimeError：SyntaxError：意外的標記：運算符（>）（行：22342，col：24，pos：826182）
我在SO上發現了一個類似的問題here，但它似乎仍然沒有解決，並且我嘗試了所有響應中的建議。
任何幫助表示讚賞。這裏是我的問題的命令行跟蹤：
ExecJS::RuntimeError: SyntaxError: Unexpected token: operator (>) (line: 22342, col: 24, pos: 826182)

當你的coffeescript無效時，你可以得到這種exec js錯誤，你確定它在開發中嗎？ –
感謝您的迴應 - 我沒有運行coffeescript。我只是有一些jQuery和反應組件。肯定本地運行良好。我在試圖在heroku中種子時遇到問題，我相信這是在生產環境中運行的？ –
