用idea鼠标点击选中的部分提示Cannot find declaration to go to

这个问题通常是因为 IDE 无法找到类型声明。让我们添加必要的类型声明：

首先在项目根目录创建 env.d.ts 文件：

/// <reference types="vite/client" />

// Vue 组件的类型声明
declare module '*.vue' {
  import type { DefineComponent } from 'vue'
  const component: DefineComponent<{}, {}, any>
  export default component
}

// 静态资源的类型声明
declare module '*.svg' {
  const content: any
  export default content
}

declare module '*.png' {
  const content: any
  export default content
}

declare module '*.jpg' {
  const content: any
  export default content
}

declare module '*.jpeg' {
  const content: any
  export default content
}

更新 tsconfig.json：

{
  "compilerOptions": {
    "target": "ES2020",
    "useDefineForClassFields": true,
    "module": "ESNext",
    "lib": ["ES2020", "DOM", "DOM.Iterable"],
    "skipLibCheck": true,

    /* Bundler mode */
    "moduleResolution": "bundler",
    "allowImportingTsExtensions": true,
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "preserve",

    /* Type Checking */
    "strict": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noFallthroughCasesInSwitch": true,

    /* Paths */
    "baseUrl": ".",
    "paths": {
      "@/*": ["src/*"]
    },
    "types": ["vite/client"]
  },
  "include": [
    "src/**/*.ts",
    "src/**/*.d.ts",
    "src/**/*.tsx",
    "src/**/*.vue",
    "env.d.ts"
  ],
  "references": [{ "path": "./tsconfig.node.json" }]
}

如果还没有 tsconfig.node.json，也创建它：

{
  "compilerOptions": {
    "composite": true,
    "skipLibCheck": true,
    "module": "ESNext",
    "moduleResolution": "bundler",
    "allowSyntheticDefaultImports": true
  },
  "include": ["vite.config.ts"]
}

安装依赖

pnpm install -D @types/node vue-router@4 @types/vue-router

在项目根目录创建或修改 tsconfig.json：

{
	"compilerOptions": {
		"target": "ESNext",
		"useDefineForClassFields": true,
		"module": "ESNext",
		"moduleResolution": "node",
		"strict": true,
		"jsx": "preserve",
		"sourceMap": true,
		"resolveJsonModule": true,
		"isolatedModules": true,
		"esModuleInterop": true,
		"lib": ["ESNext", "DOM"],
		"skipLibCheck": true,
		"baseUrl": ".",
		"paths": {
			"@/*": ["src/*"]
		},
		"types": ["node", "vue-router"],
		"outDir": "./dist"
	},
	"include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"],
	"references": [{ "path": "./tsconfig.node.json" }]
}
