vue3 + vite + ts 配置 @ 别名

npm install @types/node -D

这是原 vite.config.ts文件import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'// https://vitejs.dev/config/
export default defineConfig({plugins: [vue()],
})改成下面这个import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { resolve } from 'path'// https://vitejs.dev/config/
export default defineConfig({plugins: [vue()],resolve:{alias:{'@': resolve(__dirname,'./src')}},
})

这是原 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",/* Linting */"strict": true,"noUnusedLocals": true,"noUnusedParameters": true,"noFallthroughCasesInSwitch": true},"include": ["src/**/*.ts", "src/**/*.tsx", "src/**/*.vue"],"references": [{ "path": "./tsconfig.node.json" }]
}改成下面这样
