您好，不知道為何我輸入的!!join後，機器人完全都沒反應，不會加入頻道。

[kurega]

請問 !!join 機器人加進來後，按 !!play 加上網址 沒有跑出提示訊息及播放歌曲

[B-l-u-e-b-e-r-r-y]

@thisiskk 檢查一下：

1. 機器人有上線嗎？ 如果機器人是離線狀態，可能是 token.json 中的 token 有誤
2. 你目前正在伺服器的語音頻道裡面嗎？

如果上述兩點都有做到，看看 terminal 有沒有錯誤訊息，可以貼上來我看看是什麼問題~

[B-l-u-e-b-e-r-r-y]

@kurega 我更新了程式碼和套件版本，可以再測試看看能不能正常播放

[kurega]

可以了

請問我在撥放音樂時沒反應 而後台跑出:

請問這是什麼意思

[B-l-u-e-b-e-r-r-y]

@CatTW

問題出在這行的 musicURL 字串沒處理乾淨，前面多了一個空格

const musicURL = msg.content.replace(`${prefix}play`, '');

改為這樣應該就正常了：

const musicURL = msg.content.replace(`${prefix}play`, '').trim();

感謝回報~ Github Repo 也更新了

[RockKingdom]

npm install @discordjs/opus 用不了阿~~

[B-l-u-e-b-e-r-r-y]

@RockKingdom 剛剛測試可以正常安裝。有什麼錯誤訊息嗎？

[RockKingdom]

跑出一堆err

[hmes98318]

@RockKingdom 安裝不了可以試試用這個" npm install opusscript ", 我自己也是裝不了" npm install @discordjs/opus " 改裝另一個就可以

[hmes98318]

" npm install ffmpeg-static " 在ubuntu20.04會一直安裝失敗, 用這個網站的安裝方法(https://www.vultr.com/docs/how-to-install-the-latest-static-build-of-ffmpeg) 下去安裝有成功, 但音樂播到一半(約3分鐘)就不會繼續了

[a25814740]

// 把音量降 50%，不然第一次容易被機器人的音量嚇到 QQ this.dispatcher[guildID].setVolume(0.2);

可以使用其他指令 但是音量設定沒有成功耶

[B-l-u-e-b-e-r-r-y]

@hmes98318 之前我也遇過這樣的情況，音樂播起來很卡，而且超過一定時間就會停止播放 後來用同樣的程式碼測試，突然就正常了。播放很順暢，也不會突然停止 猜測可能跟當下的網路環境有關，換個網路試試看

[B-l-u-e-b-e-r-r-y]

@a25814740 setVolume() 這個方法不是調整機器人的使用者音量，而是播放的音量~ 也就是說從 DC 的使用者介面是看不出來有調整過的 如果用 setVolume(0.1) 和 setVolume(1) 下去比較的話，就可以感覺出差別

[B-l-u-e-b-e-r-r-y]

@white887 看起來是 token 被重複宣告了，檢查一下程式碼吧~

[arbius1008]

放歌的時候完全沒有聲音呢@@

[B-l-u-e-b-e-r-r-y]

@arbius1008 程式碼有修改過嗎？ 有錯誤訊息嗎？ 如果都沒有的話，檢查一下機器人的使用者音量看看

[allen930309]

會撥到下一首的時候，撥放清單就完全被清掉了

[B-l-u-e-b-e-r-r-y]

發現在套件完全沒有更新的情況下，會遇到放歌沒有聲音的問題 正在找尋問題和解法 Q__Q 有新進度會再上來更新

[EKoublier]

想請問一下如果中文顯示部分變亂碼要怎麼改善？

[B-l-u-e-b-e-r-r-y]

@EKoublier 是指機器人在DC發言出現亂碼嗎？

[EKoublier]

@B-l-u-e-b-e-r-r-y 是的不好意思，沒有把問題講清楚；是在 Discord機器人於指令接收後，反饋在文字頻道中會出現亂碼問題。

[B-l-u-e-b-e-r-r-y]

@EKoublier 試試看用記事本打開 discord.js 檔案，看右下角是不是 UTF-8 的格式 如果是不是 UTF-8，就另存為 UTF-8 的格式，再試著運行看看 不過我不是很確定是不是編碼問題，因為沒有遇到過 Orz

[macychan1]

@macychan1 config.json 語法錯誤 你有修改過 config.json 檔嗎？ 有的話，注意引號要用 " 而不是 ' 沒有的話檢查檔案是否為下面內容

}

[RainWolf0603]

請問大大，播放音樂一定要用網址嗎？可不可以直接搜尋

請問大大 有沒有辦法讓這機器人在幾個地方同時播放歌呢?🙏

[Linecat0305]

@Chestnut5113 就只要在要播放的群組加入就行了 但是越多地方同時放歌會越當喔（除非你電腦好）

[Chestnut5113]

@Linecat0305 A群先放機器人進去 能播歌 不過再在B群放機器人就顯示 歌曲加入隊列🤔 而且也沒有在A群播完後才開始播

[Linecat0305]

🤔🤔這我就不清楚了，你可能得諮詢更專業人員QQ

[B-l-u-e-b-e-r-r-y]

@RainWolf0603 以目前安裝的模組來說沒辦法，你可以再加入 node-ytsr 這個模組試著寫看看

[B-l-u-e-b-e-r-r-y]

@dfewyfhcvjdsye 看起來是這邊多一個分號導致的錯誤，去掉應該就 OK

playMusic(msg, guildID, musicInfo) ";" {

[B-l-u-e-b-e-r-r-y]

@Chestnut5113 本來是預計有這個功能，但沒有特別去測試，看到你的留言才發現我有個地方寫錯 Orz 已經把更新後的程式碼修改在文中和 Github Repo 了~

[B-l-u-e-b-e-r-r-y]

@Linecat0305 看起來是執行指令的目錄沒有 discord1.js 檔案 要先切換到你放程式碼的目錄才可以~ cd C:\程式碼目錄

[Chestnut5113]

@B-l-u-e-b-e-r-r-y 感謝大大~

[Chestnut5113]

還有一個問題，就是當歌沒播完就DC機器人，下次再!!play他的話會是 歌曲加入隊列🤔

Hi，可能是因為 Youtube 更新了 API，導致 node-ytdl-core 已經不起作用

可以參考這個 issue MinigetError: input stream: Status code: 404

目前只能等他們發布新版本 一旦他們發布新版本，就試著更新套件（指令：npm install ytdl-core@latest）看看能不能正常運作

node-ytdl-core 版本發布紀錄
