Parsing error: Unexpected token ＜

这个错误，恶心死我了，卡了两三个小时。。

原因：eslint。babel-eslint配置文件有错误。

.eslintrc.js

module.exports = {
  root: true,
  env: {
    node: true,
  },
  extends: [
    'plugin:vue/essential',
    'eslint:recommended',
  ],
  parserOptions: {
    parser: 'babel-eslint',
  },
  rules: {
    'no-unused-vars': 'off',
    'vue/no-unused-components': 'off',
  },
};

project.json中

  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "lint-eslint": "eslint ."
  },
