1. 项目说明

  1. 主技术栈:
    Vite + Vue3 + TypeScript
  2. 项目中版本情况:
"Vite": "3.0.0"
"Vue":	"3.2.37"
"Ts":	"4.6.4"
  1. 出现问题:
    在配置完Vite后,正常开发没问题,但是Ts类型检查报错:
    找不到模块"/xxx/xxx/xxx"或其相应的类型声明

2. 解决方法

  1. 首先要配置Vite,根据官方文档中的给出的类型说明:
Record<string, string> | Array<{ find: string | RegExp, replacement: string }>

由此可知:我们可以配置alias为一个对象,或一个 { find, replacement } 的数组

  1. 具体配置:
    在根目录中的 vite.config.ts 中加入如下配置:(以下是我个人项目配置)
import { resolve } from "path"; // 导入 path 模块,帮助我们解析路径
export default defineConfig({
  resolve: { // 这里配置需要注意:Vite新版本resolve配置改为对象形式,如下:
    alias: [
      {
        find: '@',
        replacement: resolve(__dirname, "src"),
      },
      {
        find: 'comps',
        replacement: resolve(__dirname, "src/components"),
      },
      {
        find: 'apis',
        replacement: resolve(__dirname, "src/apis"),
      },
      {
        find: 'views',
        replacement: resolve(__dirname, "src/views"),
      },
      {
        find: 'routes',
        replacement: resolve(__dirname, "src/router"),
      },
      {
        find: 'store',
        replacement: resolve(__dirname, "src/store"),
      },
      {
        find: 'utils',
        replacement: resolve(__dirname, "src/utils"),
      },
      {
        find: 'styles',
        replacement: resolve(__dirname, "src/styles"),
      },
      {
        find: 'layout',
        replacement: resolve(__dirname, "src/Layout"),
      },
      {
        find: 'models',
        replacement: resolve(__dirname, "src/models"),
      },
      {
        find: 'hooks',
        replacement: resolve(__dirname, 'src/hooks')
      }
    ],
  }
})
  1. 这样配置完成后,项目中可以正常使用,但是Ts类型检查会提示错误,接着,配置根目录下的 ts.config.json 文件:(这里还是我个人的配置,分别对应Vite中配置好的别名)

注意:主要配置 baseUrlpaths 两个配置项即可,其他选项是初始化项目自动生成的

{
  "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/*"],
      "comps/*": ["src/components/*"],
      "apis/*": ["src/apis/*"],
      "views/*": ["src/views/*"],
      "routes/*": ["src/router/*"],
      "store/*": ["src/store/*"],
      "utils/*": ["src/utils/*"],
      "styles/*": ["src/styles/*"],
      "layout/*": ["src/Layout/*"],
      "models/*": ["src/models/*"],
      "hooks/*": ["src/hooks/*"]
    }
  },
  "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"],
  "references": [{ "path": "./tsconfig.node.json" }]
}
  1. 配置完成后,Ts类型检查就不会报错了。(反应慢的重启一下VsCode)
