vue下使用ts引入@/xxx组件的问题

Question

原项目是用js写的，现在新的页面想使用ts写，但在用import引入 @ 开头的组件会报错，在js下是没有问题的

import MixinPermission from "@/mixins/Permission.vue";

Answer 1

ts 配置需要读取项目根路径的 tsconfig.json，添加 paths 配置即可：

{
  "compilerOptions": {
    "target": "esnext",
    "useDefineForClassFields": true,
    "module": "esnext",
    "moduleResolution": "node",
    "strict": true,
    "jsx": "preserve",
    "sourceMap": true,
    "resolveJsonModule": true,
    "esModuleInterop": true,
    "lib": ["esnext", "dom"],
    "paths": {
      "@/*": [
        "./src/*"
      ]
    }
  },
  "include": [
    "src/**/*.ts",
    "src/**/*.d.ts",
    "src/**/*.tsx",
    "src/**/*.vue"
  ]
}
