本文介绍了当使用eslint-loader进行语法检查时遇到'test'变量未使用导致的错误信息。通过在vue.config.js中配置关闭lintOnSave选项，可以消除该报错。重新启动项目后，报错信息成功消失，这是一个快速解决eslint未使用变量警告的方法。

1、相关报错信息

error  'test' is assigned a value but never used  no-unused-vars

2、报错原因

使用了eslint-loader进行了相关的语法检查，因为test变量没有被使用过，不符合相关的语法规则，则报错输出。

3、关闭相关语法检查

  1. 在相关项目的根目录下新建vue.config.js文件
    在这里插入图片描述
  2. 在vue.config.js文件中进行如下配置
module.exports = {
    // 关闭语法检查
    lintOnSave: false
}
  1. 最后重新启动项目后发现相关的报错信息消失

具体可参见：Vue CLI 配置参数
