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参数没有被传递或被传递为undefined.

这是堆栈跟踪：

Aborted due to warnings.

如果我注释掉过滤器函数的主体，则 assemble 会正常运行。

@tim 我们通常会在数据上下文中的属性名称和车把助手发生冲突时看到这些错误。

如果您filter在数据上下文中有一个属性，请尝试使用{{this.filter}}而不是{{filter}}给 Handlebars 一个提示，它应该使用该属性而不是助手。

这个问题来自Github 上的这个问题。我希望这可以帮助其他有同样问题的人。
