环境：

vue cli 3.0初始化带有eslint项目

触发位置：

<img class="avatar" :src="photoUrl" alt="avatar" />

解决：

报错内容是：不允许对HTML void元素进行自动关闭

方法一：

<img class="avatar" :src="photoUrl" alt="avatar">

方法二：

修改文件.eslintrc.js

...
rules: {
...
	"vue/html-self-closing": ["error", {
      "html": {
        "void": "always",
        "normal": "never",
        "component": "always"
      },
      "svg": "always",
      "math": "always"
    }],
...
}
