尽管没有在模板中使用过滤器助手，但 TypeError 会阻止组装完成。看起来 options 参数未被传递或作为 undefined 被传递。
这是堆栈跟踪:
Warning: Cannot read property 'data' of undefined Use --force to continue.

Aborted due to warnings.
如果我注释掉过滤器函数的主体，汇编将正常运行。
最佳答案
@tim 我们通常会在数据上下文中的属性名称与 handlebars 助手发生冲突时看到这些错误。
如果您在数据上下文中将 filter 作为属性，请尝试使用 {{this.filter}} 而不是 {{filter}} code> 给 Handlebars 一个提示，它应该使用属性而不是助手。
