如何修复“仅在ES6中可用”的linter错误?

标签: javascript sublimetext2 jslint eslint sublimelinter

我正在尝试为我的Express应用程序添加一个linter,并且我收到了几个关于ES6的linter错误,即‘export’ is only available in ES6 (use esnext option)’const’ is only available in JavaScript 1.7’arrow function syntax’ is only available in Javascript 1.7。我不知道如何摆脱这些错误 - 任何帮助将不胜感激。我目前已经尝试过安装一些东西,包括Sublime Text 2 linter和babel-eslint,但可能接近这个错误。

在首选项中将esnext设置为true - >包装设置 - > Sublimelinter - >设置 - 用户为我工作

{
  "jshint_options":
    {
        "esnext": true
    }
}

我认为你必须摆脱esnext 这是我的节点.eslintrc:

    {
  "extends" : "airbnb",
  "rules": {
   // disable requiring trailing commas because it might be nice to revert to
   // being JSON at some point, and I don t want to make big changes now.
   "comma-dangle": 0,
   // we can use escape and template strings
   "quotes": [1, "single", {"avoidEscape": true, "allowTemplateLiterals": true}],
   "max-len": [0],
   "no-console": 0,
   "no-param-reassign": 0
 },
 "globals": { "ENV": true },
 "env": {
    "browser": true,
    "node": true,
    "jasmine": true
  }
}

这些是我的devDependencies

  "devDependencies": {
    "babel-cli": "^6.9.0",
    "babel-core": "^6.9.0",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-stage-0": "^6.5.0",
    "eslint": "^3.1.1",
    "eslint-config-airbnb": "^12.0.0",
    "eslint-plugin-import": "1.16.0",
    "eslint-plugin-jsx-a11y": "2.2.3",
    "eslint-plugin-react": "6.4.1",
    "nodemon": "^1.9.2"
  }

ecmaFeatures配置设置在parserOptions下。

...
plugins: [
  'import'
],
parserOptions: {
    ecmaFeatures: {
        jsx: true
    },
    ecmaVersion: 6,
    sourceType: 'module'
},
...

您应该使用sourceType: 'module'代替modules: true
