找不到模块“./App.svelte”或其相应的类型声明

Question

我有一个将电子与 svelte 以及打字稿支持集成在一起的设置。

当我运行rollup脚本来编译 svelte 应用程序时，./App.svelte出现如下所示的找不到模块错误。

Plugin typescript: @rollup/plugin-typescript TS2307: Cannot find module './App.svelte' or its corresponding type declarations.

这是我的package.json配置：

Answer 1

原来我必须先@tsconfig/svelte作为开发依赖项安装，然后用我的扩展它，tsconfig.json如下所示：

安装@tsconfig/svelte

npm i --save-dev @tsconfig/svelte

将此 tsconfig 添加为您的基本配置文件tsconfig.json：

{
  "extends": "@tsconfig/svelte/tsconfig.json",
}

Answer 2

我这边的罪魁祸首是一个陈旧的人global.d.ts。我已经/// <reference types="@sveltejs/kit" />设置了，但正在尝试将项目更改为 vanilla Svelte。修复它就达到/// <reference types="svelte" />了目的。

如果Natesh 的答案不适合你，这个文件应该作为一个基本的垫片：

// svelte-shim.d.ts

declare module "*.svelte" {
    import type { ComponentType } from "svelte";
    const component: ComponentType;
    export default component;
}

这本质上告诉 TypeScript 任何它不知道如何处理的 .svelte 文件都应该作为 Svelte 组件读入。您不会获得他们导出的任何道具或方法，但如果您需要的只是使用他们的基本ComponentType界面，那么这应该可以正常工作。
