类型“LodashReplace1x5”不可分配给类型“字符串”

Question

我在 typescript 中使用 lodass/fp 时遇到了一个奇怪的问题。 它有效，但显示错误。 我不知道为什么会这样。

这是错误：

TS2769: No overload matches this call.   Overload 1 of 3, '(callbackfn: (previousValue: string, currentValue: string, currentIndex: number, array: string[]) => string, initialValue: string): string', gave the following error.     Argument of type '(acc: string, curr: string) => fp.LodashReplace1x5' is not assignable to parameter of type '(previousValue: string, currentValue: string, currentIndex: number, array: string[]) => string'.       Type 'LodashReplace1x5' is not assignable to type 'string'.   Overload 2 of 3, '(callbackfn: (previousValue: string, currentValue: string, currentIndex: number, array: string[]) => string, initialValue: string): string', gave the following error.     Argument of type '(acc: string, curr: string) => fp.LodashReplace1x5' is not assignable to parameter of type '(previousValue: string, currentValue: string, currentIndex: number, array: string[]) => string'.       Type 'LodashReplace1x5' is not assignable to type 'string'.

问题是什么？ 我该如何解决？

Answer 1

我认为它会检测到类型，但似乎我们必须明确地告诉类型，如下图所示：
