“错误：$ injector：nomod模块不可用”

Question

你好有人知道我为什么不显示3而不是{{remaining}}？我收到了错误： “错误：$ injector：nomod模块不可用”。 我的片段在这里工作，但我不知道为什么它对我不起作用

let arrayValue = arr[i]

if let value = dict[cha] {
    if value != arrayValue {
        return false
    }
} else {
    if dict.values.contains(arrayValue) { // maybe this? it's hard to guess
        return false
    }

    dict[cha] = arrayValue
}
