vue.js - "Parsing error: Unexpected token < ..."使用 VueCli3 和 airbnb eslint

Question

我知道这似乎是一个重复的问题，在尝试以下操作后，我仍然遇到这种类型的 eslint 错误:

https://github.com/prettier/prettier/issues/3720 (我已经安装了 eslint-plugin-vue)

Vue.js eslint Parsing error .: unexpected token (与我的问题并不真正相关，但我还是尝试了)

https://github.com/vuejs/eslint-plugin-vue/issues/186

"Unexpected token <" for VueJS running with Webpack

这是我的 package.json 设置的一部分:

"devDependencies": {
    "@vue/cli-plugin-babel": "^3.0.5",
    "@vue/cli-plugin-eslint": "^3.0.5",
    "@vue/cli-plugin-unit-jest": "^3.0.5",
    "@vue/cli-service": "^3.0.5",
    "@vue/eslint-config-airbnb": "^4.0.0",
    "@vue/test-utils": "^1.0.0-beta.20",
    "babel-core": "7.0.0-bridge.0",
    "babel-eslint": "^10.0.1",
    "babel-jest": "^23.6.0",
    "eslint": "^5.8.0",
    "eslint-config-airbnb-base": "^13.1.0",
    "eslint-plugin-import": "^2.14.0",
    "eslint-plugin-vue": "^5.0.0-0",
    "vue-template-compiler": "^2.5.17"
  },
  "eslintConfig": {
    "root": true,
    "env": {
      "node": true
    },
    "extends": [
      "plugin:vue/essential",
      "@vue/airbnb"
    ],
    "rules": {},
    "parserOptions": {
      "parser": "babel-eslint",
      "ecmaVersion": 6
    }
  },

这是我的 .eslintrc.js文件:

module.exports = {
  parserOptions: {
    sourceType: 'module',
    allowImportExportEverywhere: true,
  },
  rules: {
    'no-console': 0,
  },
  plugins: ['vue'],
};

这是 eslint 错误的详细版本:

error: Parsing error: Unexpected token < at src/App.vue:1:1:
> 1 | <template>
    | ^
  2 |   <div id="app">
  3 |     <router-view/>
  4 |   </div>

这是我的 App.vue 源代码:

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
export default {
  name: 'BuilderApp',
  data() {
    return {
      dragEvents: ['drag', 'dragstart', 'dragend', 'dragover', 'dragenter', 'dragleave', 'drop'],
    };
  },
  mounted() {
    // prevent default action for all defined dragEvents
    if (this.dragAndDropCapable()) {
      this.dragEvents.forEach((dragEvent) => {
        document.getElementById('app').addEventListener(dragEvent, (e) => {
          e.preventDefault();
          e.stopPropagation();
        }, false);
      });
    }
  },
  methods: {
    dragAndDropCapable() {
      const testDiv = document.createElement('div');
      return (('draggable' in testDiv)
          || ('ondragstart' in testDiv && 'ondrop' in testDiv))
          && 'FormData' in window
          && 'FileReader' in window;
    },
  },
};
</script>

<style>
.filter-disable .filter-count {
  background: #dadada;
}
</style>

我不确定我错过了什么。
感谢您的时间和帮助!

您错过了 .eslintrc 中的“解析器”文件。

这是我的 .eslintrc

{
  "parser": "vue-eslint-parser",
  "parserOptions": {
    "ecmaVersion": 7,
    "sourceType": "module"
  }
}
