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)
