Question

我已经为node.js安装了MySQL，但是我的代码没有更新数据库。我使用$output = shell_exec('awk -F, \'NR==FNR{seen[$0]++;next} ($1 in seen)\' uploads/a.txt uploads/b.txt > exports/output.txt');在本地服务器上运行代码要使我的node robot.js工作该怎么办？

我在代码中做了很多更改（我不知道自己所做的所有更改） -删除query() -更改我的SQL代码 -在mysql.format()

中更改我的回调函数

robot.js

query()

database_boxy.js

        callback(null, 'one');
        await browser.close();

    },
], function (err, result1) {
    util.promisify(process.exit());
})

与数据库的连接正常，并且我没有任何错误消息，但是它没有更新。

谢谢！
