TypeError: Cannot read property 'id' of null

Question

exports.delGuild = function(guild){
  db.run("DELETE FROM guilds WHERE id = ?", guild.id, (err, result) => {
    if (err) return console.log(err.message);
    console.log(`guild ${guild.id} removed from database`);
  });
}

我不知道为什么有时会发生这种情况，但程序会崩溃。

Answer 1

确保你正确定义了公会，当你调用delGuild函数时，确保你是这样调用它的； file.delGuild(guild)
