奇怪的夹板错误＆＃34;解析错误：意外的令牌=（致命）＆＃34;

Question

我试图在反应应用中设置auth0并且此错误在我的auth0= new auth0.WebAuth({初始化时不断弹出，我尝试使用/* eslint-disable */禁用eslint但是它已经＃39 ; s不工作。

这是我的Auth.js文件：

// imports EventEmitter
import { EventEmitter } from 'events';
// imports the Auth0 JS library
import auth0 from 'auth0-js';
// imports Auth0 credentials from the auth0-variables.js file
import { AUTH_CONFIG } from './auth0-variables';
// imports the history module, which will be created later
import history from '../history';

export default class Auth extends EventEmitter {
    // An instance of Auth0 is instantiated with Auth0 credentials gotten from the auth0-variables.js file


    auth0 = new auth0.WebAuth({ //this is where I'm getting the error

    domain: AUTH_CONFIG.domain,
    clientID: AUTH_CONFIG.clientId,
    redirectUri: AUTH_CONFIG.callbackUrl,
    audience: `https://${AUTH_CONFIG.domain}/userinfo`,

    // Telling Auth0 what to return after a successful authentication, in this case, the token and the id_token
    responseType: 'token id_token',

    // To retrieve a user's profile after authentication, we need to add openid profile to the the scope.
    scope: 'openid profile'
  });

这是我的.eslint：

类实例属性（类体内的auth = new auth0.WebAuth(/*...*/);）仍然是实验性的。如果您有兴趣，可以follow development of the proposal - 截至撰写本文时，它位于tc39 proposal process的第3阶段。

如果你想今天使用类属性（我看到你正在使用React，它们在React代码中很常见），并且假设你已经设置了Babel，ESLint可以解析它们和其他实验性功能babel-eslint的帮助。自述文件有更完整的说明，但您需要npm install --save-dev babel-eslint并将"parser": "babel-eslint"添加到.eslintrc.json。
