如何在 .vue 文件中导入类(.js 文件)?
我有一个名为 Authenthicator 的类,它位于文件 Authenticator.js 中。我想在我的 vue 应用程序中使用它的功能,特别是在文件 Login.vue 中。
如何导出 Authenticator 类并将其导入 Login.vue?
我收到以下错误:
Uncaught TypeError:无法读取未定义的属性“match” at patch (webpack-internal:///./node_modules/graceful-fs/polyfills.js:31) at patch (webpack-internal:///./node_modules/graceful-fs/graceful-fs.js:96) at Object.eval (webpack-internal:///./node_modules/graceful-fs/graceful-fs.js:88) at eval (webpack-internal:///./node_modules/graceful-fs/graceful-fs.js:348) at Object../node_modules/graceful-fs/graceful-fs.js (chunk-vendors.js:10849) 在 webpack_require (app.js:785) 在 fn (app.js:151) 在 Object.eval (webpack-internal:///./node_modules/gulp-sourcemaps/src/init/index.internals.js:9) 在 eval (webpack-internal:///./node_modules/gulp-sourcemaps/src/init/index.internals.js:124) 在 Object../node_modules/gulp-sourcemaps/src/init/index.internals.js (chunk-vendors.js:11038)

谢谢
export default class Authenticator {
// ...
}
并导入文件:
import Authenticator from "path/to/file/authenticator.js
var Auth = new Authenticator ();
如果没有您的代码,很难提供帮助,但这里有一个基本示例:
Authenticator.js
'use strict';
class Authenticator {
// ...
};
module.exports.Authenticator = Authenticator;
Login.vue
<script>
import Authenticator from 'path/to/Authenticator.js';
const AuthenticatorInstance = new Authenticator;
// use it...
</script>
Authenticator.js
class Authenticator {
//
};
export default new Authenticator;
Login.vue
<script>
import Authenticator from 'path/Authenticator';
</script>
