Typescript「導出的外部封裝類型不是一個模塊」

Question

我想創建我的第一個Typescript定義文件。主題代碼是filename.js（index.js）：

module.exports = { 
    extension: extension, 
    basename: basename, 
    removeSuffix: removeSuffix, 
    removeSuffixWithDelimiter: removeSuffixWithDelimiter, 
    appendSuffix: appendSuffix, 
    appendSuffixWithDelimiter: appendSuffixWithDelimiter, 
    directoryName: directoryName 
} 
function extension(filename) {} 
function basename(filename) {} 
function removeSuffix(filename) {} 
function removeSuffixWithDelimiter(delimiter, filename) {} 
function appendSuffix(suffix, filename) {} 
function appendSuffixWithDelimiter(suffix, delimiter, filename) {} 
function directoryName(filename) {} 

定義（index.d.ts）文件我到目前爲止有：

declare module "filename.js" { 
    export function extension(filename: string): string; 
    export function basename(filename: string): string; 
    export function removeSuffix(filename: string): string; 
    export function removeSuffixWithDelimiter(delimiter: string|number, filename: string): string; 
    export function appendSuffix(suffix: string, filename: string): string; 
    export function appendSuffixWithDelimiter(suffix: string, delimiter: string|number, filename: string): string; 
    export function directoryName(filename: string): string; 
} 

此作品不夠好（自動完成的作品在我的編輯），但我得到一個編譯錯誤：

index.ts(21,29): error TS2656: Exported external package typings file 'filename.js/index.d.ts' is not a module. Please contact the package author to update the package definition.

這個錯誤是什麼意思（新打字稿），更重要的是，我應該怎麼修改我的定義，使之更正確？

Answer 1

爲您提供的數據定義文件可以是： -

declare module customTypings{ 
interface filename{ 
    extension(filename: string): string; 
    basename(filename: string): string; 
    removeSuffix(filename: string): string; 
    removeSuffixWithDelimiter(delimiter: string|number, filename: string): string; 
    appendSuffix(suffix: string, filename: string): string; 
    appendSuffixWithDelimiter(suffix: string, delimiter: string|number, filename: string): string; 
    directoryName(filename: string): string; 
} 
} 

您可以通過指定使用此類型的文件： -

/// <reference path="pathName" /> 

看看它是否工作。
