Ruby on rails 资源预编译中的Rails嵌套表单文件错误

Rails告诉我，application.js中有一些错误

$ rake assets:precompile
/usr/bin/ruby1.8 /usr/local/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
rake aborted!
Unexpected token: operator (*=) (line: 12013, col: 1, pos: 341357)

当我删除这一行时，它告诉我它找不到嵌套的表单文件

编辑：

当我生成//=require jquery\u嵌套\u表单时，它会生成以下内容：

$ rake assets:precompile
/usr/bin/ruby1.8 /usr/local/bin/rake assets:precompile:all RAILS_ENV=production            RAILS_GROUPS=assets
rake aborted!
couldn't find file 'prototype_nested_form'

我确信你的语法是错误的。看看这篇文章：

你的语法正确吗？你为什么用“*”？我被一些芭蕾舞团迷住了。我不知道这是怎么回事。但当我删除“*”时，只有以下问题存在：意外标记：运算符（=）…请使用

/=require-prototype\u-nested\u-form

编辑的问题重试。找不到嵌套表单文件…请阅读我在下面发布的链接-我想您还需要包含它
