找不到模块“./App.svelte”或其相应的类型声明

我有一个将电子与 svelte 集成以及打字稿支持集成的设置。

当我运行rollup编译 svelte 应用程序的脚本，我找不到模块./App.svelte错误如下图所示。

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

这是我的package.json配置 ：

原来我必须安装@tsconfig/svelte首先作为开发依赖项，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",
}
