先将vscode升级到最新，卸载vetur，安装volar（vue official）。

再安装vscode的eslint。

在vue项目下创建.eslintrc.js

配置如下

module.exports = {
    root: true,
    env: {
        browser: true,
        es6: true,
        node: true
    },
    extends: [
        'eslint:recommended',
        'plugin:vue/vue3-recommended',
    ],
    plugins: [
        'vue',
    ],
    globals: {
        defineProps: "readonly",
        defineEmits: "readonly",
        defineExpose: "readonly",
        withDefaults: "readonly",
    },
    rules: {
        'vue/multi-word-component-names': 'off', // 接触文件名限制
        "vue/html-self-closing": ["error", { // 闭合标签验证逻辑处理
            "html": {
                "void": "always",
                "normal": "never",
                "component": "always"
            },
            "svg": "always",
            "math": "always"
        }]
    }
};
