javascript - 无法使用 Combres 和 yui 缩小

Question

我不确定如何找出更多关于我的 .js 文件有什么问题的信息，但是如果我将“defaultDebugEnaled = true”设置为“defaultDebugEnaled = true”，那么它可以正常工作，但将其设置为“false”会使我收到此错误

而且我似乎无法切换任何东西来使它给我一个更具体的错误，我只知道在尝试缩小它时它失败了。

此外，只有当我包含一个特定文件时才会发生这种情况，但这是可行的，所以不能只发布该文件。

“缺少形式参数”意味着函数定义缺少参数。例如

/**
 * @param x ...
 * @param y ...
 */
function f(x) {  // Only one formal parameter.
  ...
}

f(1, 2);  // Called with 2 actual parameters.

函数 f 缺少形式参数 y。

编辑:

https://github.com/wycats/handlebars.js/issues/93讨论了一个类似的问题，并提出问题是 YUI 压缩器将某些 JS 标识符(错误地)视为保留字，并在将保留字用作形式参数时发出此错误

$ java -jar lib/closurecompiler.jar --js js/handlebars.1.0.0.beta.3.js 
js/handlebars.1.0.0.beta.3.js:667: ERROR - Parse error. missing formal parameter
Handlebars.AST.BooleanNode = function(boolean) {

I have a version that seems to be working in my fork. Main change was to remove reserved word with s/boolean/bool/gAlso linted the input .js files for consistency.
