vue.js - TypeScript 路径别名 - 如何修复导入错误

我使用 Vue CLI 3 生成了 Vue.js 项目，并使用 @ 别名编写了 import 语句。当我执行 npm run build 时，发生了导入错误。为什么？

错误信息

npm run build

> [email  build /Users/???/Desktop/example
> vue-cli-service build

        "src/main/javascript/*",
        "src/test/javascript/*"
      ]
    },

export default class Member {
 ...
}

import Member from '@/models/Member'; // import error

语法高亮

我的 VSCode 可以检测到导入错误，但使用 @ 别名时却无法检测到。

答案＃1

你可以在 vue.config.js 中使用 configureWebpack 或 chainWebpack 来设置你自己的别名

vue.config.js

const path = require('path')
module.exports = {
  chainWebpack: config => {
        config.resolve.alias
        .set('@', path.resolve(__dirname, 'src/main/javascript'));
  }
}
