Ruby on rails 尝试在RoR中为生产预编译资产时出现ExecJS运行时错误

我最近尝试预编译Rails 4.2.6 CMS应用程序的资产，但出现以下错误：

** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Execute assets:precompile
rake aborted!
ExecJS::RuntimeError: SyntaxError: Unexpected token: name (type) (line: 5338, col: 20, pos: 251597)
