解决

个人原因: 路径不能有中文

其他方案

1. 删除 dist 目录并再次运行： npm run start:dev

2. tsconfig.json 中添加 "paths": { "src/*": ["src/*"] }

3. package.json文件中 jest 节点中添加

       "moduleNameMapper": {
         "^src/(.*)$": "<rootDir>/$1"
       },
   

4. 删除tsconfig.json 文件noEmit

5. jest-e2e.json中transform节点添加 "^src/(.*)": "<rootDir>/../src/$1"
