注意，是jest-html-reporters，不是jest-html-reporter

一、直接安装

npm install jest-html-reporters

二、在jest.config.js中添加配置文件

const moment = require('moment');
const date = moment(new Date()).format('YYYY-MM-DD-HH-mm-ss');
module.exports = {
    testEnvironment: "node",
    reporters:[
        "default",
        [
            "jest-html-reporters",
            {
                "pageTitle":"Jest Report",
                "filename":`./report/child/${date}.html`,
                "expand":true
            }
        ]
    ],
};

filename中的目录需要提前建好
