eslint:错误解析错误:关键字'const'被保留 [英] eslint: error Parsing error: The keyword 'const' is reserved

问题描述

我从 ESLint 收到此错误:

I am getting this error from ESLint:

error  Parsing error: The keyword 'const' is reserved

来自此代码:

const express = require('express');
const app = express();
const _ = require('underscore');

我尝试删除 node_modules 并重新安装所有 npm 包(如建议的 此处)，但无济于事.

I've tried removing node_modules and reinstalling all npm packages (as suggested here), but to no avail.

推荐答案

ESLint 默认使用 ES5 语法检查.您需要覆盖到最新的受良好支持的 JavaScript 版本.

ESLint defaults to ES5 syntax-checking. You'll want to override to the latest well-supported version of JavaScript.

尝试将 .eslintrc 文件添加到您的项目中.里面:

Try adding a .eslintrc file to your project. Inside it:

{
    "parserOptions": {
        "ecmaVersion": 2017
    },

    "env": {
        "es6": true
    }
}

希望这会有所帮助.

我还发现了 这个示例 .eslintrc帮助.

I also found this example .eslintrc which might help.
