RuntimeError:使用语音所需的PyNaCl库

Question

Traceback (most recent call last):
  File "C:\Users\Pradeep Tejwani\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\bot.py", line 892, in invoke
    await ctx.command.invoke(ctx)

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: RuntimeError: PyNaCl library needed in order to use voice

即使我同时安装了python库pynacl和discord.py[voice]，这也是我的错误。我试了很多次，但还是得到了同样的错误。我甚至将我的库更新到了更新的版本，但没有任何变化。

代码：

@bot.command()
async def join(ctx):
    channel = ctx.message.author.voice.channel
    voice = get(bot.voice_clients, guild=ctx.guild)

    if voice and voice.is_connected():
        await voice.move_to(channel)
    else:
        voice = await channel.connect()

    await voice.disconnect()

    if voice and voice.is_connected():
        await voice.move_to(channel)
    else:
        voice = await channel.connect()
        print(f"The bot has connected to {channel}\n")

    await ctx.send(f"Joined {channel}")

#leave cmd
@bot.command()
async def leave(ctx):
    channel = ctx.message.author.voice.channel
    voice = get(bot.voice_clients, guild=ctx.guild)

    if voice and voice.is_connected():
        await voice.disconnect()
        print(f"The bot has left {channel}")
        await ctx.send(f"Left {channel}")
    else:
        print("Bot was told to leave voice channel, but was not in one")
        await ctx.send("Don't think I am in a voice channel")

Answer 1

你安装PyNaCl了吗？如果未安装，请从PyPi下载PyNaCl或安装discord.py或的Voice Version，然后在控制台中键入以下内容

python3 -m pip install -U discord.pyvoice

注意: Discord.py现在是1.5.1版(我不知道您是否更新了)，而PyNaCl现在是1.4.0以上的版本

Answer 2

你必须安装PyNaCl才能正常工作！您可以在终端中尝试使用pip install PyNaCl或pip3 install PyNaCl，也可以尝试将以下代码片段粘贴到代码顶部：

import os, platform
try:
    import nacl
except ImportError:
    try:
        if platform.system().lower().startswith('win'):
            os.system("pip install pynacl")
        else:
            os.system("pip3 install pynacl")
    except Exception as e:
        print("Error:", e)
        exit()

如果这段代码丢失了，它将被下载！
