Question

我有以下错误

UnhandledPromiseRejectionWarning: Error: SQLITE_ERROR: table scores has no column named points

有人知道修复吗？

我也使用discord.js命令，所以我的用户在run ...

中定义

代码：

run(msg, {user, reason}) {
        msg.delete()
        if(!user) {msg.say(`**Cannot find user! Make sure it's a valid member of this server!**`)
     } else {
            msg.say(`**${user.tag} has been warned for ${reason}!**`)   
            sqlite.get(`SELECT * FROM scores WHERE userId = "${user.id}"`).then(row =>{
                    if (!row) {
                        sqlite.run("INSERT INTO scores (userId, points) VALUES (?,?)", [user.id, 1])
                    } else {
                        sqlite.run(`UPDATE scores SET points = ${row.points  + 1} WHERE userId = ${user.id}`)
                    }
                }).catch(()=>{
                   sqlite.run(`CREATE TABLE OF NOT EXISTS scores (userId TEXT, points INTEGER)`).then(()=> {
                     sqlite.run(`INSERT INTO scores (userId, points) VALUES (?, ?)`, [user.id, 1])
                })
            })
            
            
        }

你需要将承诺链接起来以便那样捕捉它们。

sqlite.get(`SELECT * FROM scores WHERE userId = "${user.id}"`).then(row =>{
  if (!row) {
      return sqlite.run("INSERT INTO scores (userId, points) VALUES (?,?)", [user.id, 1])
  } else {
      return sqlite.run(`UPDATE scores SET points = ${row.points  + 1} WHERE userId = ${user.id}`)
  }
}).catch(()=>{
 return sqlite.run(`CREATE TABLE OF NOT EXISTS scores (userId TEXT, points INTEGER)`).then(()=> {
    return sqlite.run(`INSERT INTO scores (userId, points) VALUES (?, ?)`, [user.id, 1])
}).catch((err) => {
  console.error(err);
});

Discord.js SQLITE_ERROR：表分数没有列名为points的列
