ESlint error with React class, for example: "state" is undefined. (No-UNDEF)

I am really working on a project and when I cloned my project on a MacBook, then yarnin the shell for installing packages and atom .for opening my ATOM. ESLint received an "error".

For example, for this code:

/*
 * Package Import
 */
 import React, { Component } from 'react';
 import PropTypes from 'prop-types';
 import { Link } from 'react-router-dom';
 import classNames from 'classnames';


/*
 * Code
 */
class UserDropdown extends Component {
  /*
   * PropTypes
   */
   static propTypes = {
     ... // Code 
   }


  /*
   * State
   */
   state = {
     ... // Code
   };

  /*
   * Actions
   */
   onLogOut = () => {
     ... // Code
   };

ESLint tell me:

Error   ESLint  'propTypes' is not defined. (no-undef)  22:10
Error   ESLint  'state' is not defined. (no-undef)  32:3
Error   ESLint  'onLogOut' is not defined. (no-undef)   52:3

I still use "babel-plugin-transform-class-properties": "^6.24.1", and I declare this in my brunch-config:

My brunch-config.coffee

  plugins:
    babel:
      presets: ['latest', 'react']
      plugins: [
        'transform-class-properties'
        'transform-object-rest-spread'
      ]

My.eslintrc

{
  "extends": "airbnb",
  "parser": "babel-eslint",
  "env": {
    "browser": true
  },
  "rules": {
    "brace-style": ["error", "stroustrup"],
    "no-param-reassign": ["error", { "props": false }],
    "no-mixed-operators": ["error", { "allowSamePrecedence": true }],
    "jsx-a11y/no-static-element-interactions": "off",
    "react/jsx-filename-extension": "off",
    "react/forbid-prop-types": "off",
    "react/no-unescaped-entities": "off",
    "linebreak-style": "off"
  },
  "settings": {
    "import/resolver": {
      "node": {
        "paths": ["app/"]
      }
    }
  }
}

And my Packages.json

"devDependencies": {
"auto-reload-brunch": "^2.7.1",
"autoprefixer": "^6.7.7",
"babel-brunch": "^6.1.1",
"babel-eslint": "^7.2.3",
"babel-plugin-transform-class-properties": "^6.24.1",
"babel-plugin-transform-object-rest-spread": "^6.23.0",
"babel-preset-react": "^6.24.1",
"babel-register": "^6.24.1",
"babel-resolver": "^1.1.0",
"brunch": "^2.10.9",
"chai": "^3.5.0",
"enzyme": "^2.8.2",
"eslint": "^3.19.0",
"eslint-config-airbnb": "^14.1.0",
"eslint-import-resolver-node": "^0.3.0",
"eslint-plugin-import": "^2.2.0",
"eslint-plugin-jsx-a11y": "^4.0.0",
"eslint-plugin-react": "^6.10.3",

I work on 2 computers, and on Linux - OK. So does anyone have an idea? If you need more code to understand, I can send it. Thanks dude!
