[klren0312]

解决方法

安装vue-eslint-parser; 配置parserOptions.tsconfigRootDir为tsconfig.json路径, parserOptions.extraFileExtensions配置['.vue']

  parser: 'vue-eslint-parser',
  parserOptions: {
    ecmaVersion: 'latest',
    sourceType: 'module',
    parser: '@typescript-eslint/parser',
    project: ['./tsconfig.json'],
    tsconfigRootDir: __dirname,
    extraFileExtensions: ['.vue']
  },

完整配置

module.exports = {
  env: {
    browser: true,
    es2021: true
  },
  extends: [
    'standard-with-typescript',
    'plugin:vue/vue3-essential'
