// NOTE: These definitions support NodeJS and TypeScript 3.2 and above.

// NOTE: TypeScript version-specific augmentations can be found in the following paths:
//          - ~/base.d.ts         - Shared definitions common to all TypeScript versions
//          - ~/index.d.ts        - Definitions specific to TypeScript 2.1
//          - ~/ts3.2/index.d.ts  - Definitions specific to TypeScript 3.2

// Reference required types from the default lib:
/// <reference lib="es2015" />

// Base definitions for all NodeJS modules that are not specific to any version of TypeScript:
/// <reference path="base.d.ts" />

// TypeScript 3.2-specific augmentations:

以下2行を修正
■修正前

index.d.ts

/// <reference lib="es2015" />
/// <reference path="base.d.ts" />

■修正後

index.d.ts

// <reference lib="es2015" />
// <reference path="base.d.ts" />

これで動くようになった
