grunt-jsxhint 和 jsxhint 的行为不一样

Question

当我使用 npm install -g jsxhint 时，我可以用它来检查我的 jsx 代码，就像这样：

但是当我尝试使用 grunt-jsxhint 设置 lint 命令时，它失败了：

我的 Gruntfile 非常简单：

module.exports = function(grunt) {

  grunt.loadNpmTasks('grunt-jsxhint');

  /* Project configuration */
  grunt.initConfig({
    options: {
      jshintrc: '.jshintrc',
      ignores: [],
      additionalSuffixes: ['.js', '.ios.js']
    },
    jshint: {
      all: ['./app/index.ios.js']
    }
  });

  /* Test Tasks */
  grunt.registerTask('test', ['jshint']);
};

为什么这些输出不同的结果？

JsxHint 和 JSHint 不是检查 JSX 的最佳工具。 JSHint 不支持 JSX，所有 JsxHint 所做的就是转换 JSX，然后在转换后的代码上运行 JSHint。我一直在使用（并强烈推荐）ESLint with the React plugin. This is better since Eslint can parse any Javascript flavor using custom parsers (like esprima-fb)

示例 .eslintrc 文件：

{
    "parser": "esprima-fb",
    "env": {
        "browser": true,
        "node": true
    },

    "rules": {
        "no-mixed-requires": [0, false],
        "quotes": [2, "single"],
        "strict": [1, "never"],
        "semi": [2, "always"],
        "curly": 1,
        "no-bitwise": 1,
        "max-len": [1, 110, 4],
        "vars-on-top": 0,
        "guard-for-in": 1,
        "react/display-name": 1,
        "react/jsx-quotes": [2, "double", "avoid-escape"],
        "react/jsx-no-undef": 2,
        "react/jsx-sort-props": 0,
        "react/jsx-uses-react": 1,
        "react/jsx-uses-vars": 1,
        "react/no-did-mount-set-state": 2,
        "react/no-did-update-set-state": 2,
        "react/no-multi-comp": 0,
        "react/no-unknown-property": 1,
        "react/prop-types": 2,
        "react/react-in-jsx-scope": 1,
        "react/self-closing-comp": 1,
        "react/wrap-multilines": 2
    },

    "ecmaFeatures": {
        "jsx": true
    },

    "plugins": [ "react" ],

    "globals": {
        "d3": true,
        "require": "true",
        "module": "true",
        "$": "true",
        "d3": "true"
    }
}

我发现我的 Gruntfile 出了什么问题。

您需要将任务加载到：grunt.loadNpmTasks('grunt-jsxhint');

设置grunt.initConfig({})后

这看起来像这样：

module.exports = function(grunt) {

  /* Project configuration */
  grunt.initConfig({
    options: {
      jshintrc: '.jshintrc',
      ignores: [],
      additionalSuffixes: ['.js', '.ios.js']
    },
    jshint: {
      all: ['./app/index.ios.js']
    }
  });

  grunt.loadNpmTasks('grunt-jsxhint');

  /* Test Tasks */
  grunt.registerTask('test', ['jshint']);
};

grunt-jsxhint 和 jsxhint 的行为不一样

grunt-jsxhint and jsxhint not acting the same

javascript

gruntjs

react-native

jsxhint
