如何解决解析错误：无法读取未定义null的属性'ecmaFeatures'？

Question

想将Eslint，React和Cypress与essint cypress preprossor一起使用

1. 我用CodeMix创建一个React项目
2. 安装cypess
3. 安装esslint
4. 安装插件

package.json看起来像这样

{
    "name": "react-hello-world",
    "version": "1.0.0",
    "description": "React Hello World",
    "main": "index.js",
    "scripts": {
        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test --env=jsdom",
        "eject": "react-scripts eject",
        "cypress:open": "cypress open",
        "cypress:run": "cypress run",
        "eslint": "eslint"
    },
    "author": "CodeMix",
    "license": "ISC",
    "dependencies": {
        "react": "^16.2.0",
        "react-dom": "^16.2.0",
        "react-scripts": "^1.1.1"
    },
    "devDependencies": {
        "cypress": "^3.1.0",
        "cypress-eslint-preprocessor": "^1.2.1",
        "eslint": "^5.6.0",
        "eslint-config-standard": "^12.0.0",
        "eslint-plugin-cypress": "^2.0.1",
        "eslint-plugin-import": "^2.14.0",
        "eslint-plugin-node": "^7.0.1",
        "eslint-plugin-promise": "^4.0.1",
        "eslint-plugin-react": "^7.11.1",
        "eslint-plugin-standard": "^4.0.0"
    }
}

.eslintrc.json看起来像这样

{
    "extends": [
        "standard",
        "eslint:recommended",
        "plugin:react/recommended",
        "plugin:import/errors",
        "plugin:import/warnings",
        "plugin:node/recommended",
        "plugin:promise/recommended"
    ],
    "plugins": [
        "react",
        "cypress",
        "import",
        "node",
        "promise"
    ],
    "rules": {
        "react/jsx-uses-react": "error",
        "react/jsx-uses-vars": "error"
    },
    "env": {
        "cypress/globals": true
    },
    "settings": {
        "react": {
            "createClass": "createReactClass",
            "pragma": "React",
            "version": "16.5.2"
        },
        "propWrapperFunctions": ["forbidExtraProps"]
    },
    "parserOptions": {
        "ecmaVersion": 9,
        "ecmaFeatures": {
            "jsx": true
        }
    }
}

cypress插件看起来像这样：

// cypress/plugins/index.js
const cypressEslint = require('cypress-eslint-preprocessor');

module.exports = (on) => {
    on('file:preprocessor', cypressEslint());
}

执行npm run cypress：run会给出错误：

  

运行：examples / actions.spec.js ...（第1个，共19个）

     

错误   /Users/stein/Development/TimeLogging/TimeLogging/cypress/integration/examples/actions.spec.js

     

cypress / integration / examples / actions.spec.js未定义：未定义   错误分析错误：无法读取未定义的属性'ecmaFeatures'   空

如何解决此错误？
