我正在使用来自npm(sqlite module)的not sqlite3。
我需要在数据库的每一行上使用异步函数。但是,任何异步代码都会导致错误。
以下代码段
async function scanDatabase() {
console.log("Scanning database...");
sql
.each(`SELECT * FROM users`, async function(err, row) {
if (err) console.log(err);
console.log(row);
let member = await guild.fetchMember(row.id);
console.log(member);
console.log(row.id);
console.log(member.user.username);
})
.then(function() {
console.log("finished scanning the database");
});
}
产生以下内容:
Scanning database...

first_payment: '2018-03-09T11:26:26.989Z',
last_payment: '2018-03-09T12:56:19.784Z',
expires: '2018-03-16T10:26:26.987Z' }

我得到了未处理的承诺错误,但我不知道如何修复"错误:提供了无效或未缓存的ID。"
