Question

我正在制作一个不和谐的机器人，如果我在聊天中键入$ join，我希望该机器人加入我所在的语音通道并播放随机声音。

case"join":
            message.delete( {timeout: 5000})
            const voiceChannel = message.member.voice.channel

            if(voiceChannel) {
                const connection = await voiceChannel.join()
                const soundFile = fs.readFileSync("./sounds/")
                const randFiles = soundFile[Math.floor(Math.random() * randFiles.length)]
                const dispatcher = connection.play(randFiles)
            } else {
                message.reply("you need to be in a voice channel!").then(message => message.delete( {timeout: 5000}))
            }
            break;

我收到此错误：

Answer 1

fs.readFileSync("./sounds/")用于读取文件的内容。您可能正在寻找fs.readdirSync("./sounds/")，该目录会为您提供目录中的一系列文件。

Answer 2

您阅读过documentation for readFileSync()吗？ readFileSync()成功在目录路径上成功返回数据的唯一操作系统是FreeBSD。

相反，您要尝试执行的操作是在目录路径中获取文件列表；为此，您可以使用fs.readdirSync()：

const soundFile = fs.readdirSync("./sounds/")
