机器人代码 #

import discord
import os
from dotenv import load_dotenv
load_dotenv()
intents = discord.Intents.default()
intents.typing = False
intents.presences = False
client = discord.Client(intents=intents)

@client.event
async def on_ready():
    print('We have logged in as {0.user}'.format(client))

@client.event
async def on_message(message):
    if message.author == client.user:

client.run(os.getenv("K"))

修复步骤 #

核心问题是Token未正确加载或验证失败，以下是针对性排查方案：

• 检查.env文件的位置和格式

  • 确保.env文件和你的Python脚本（ppap）在同一目录下
  • .env文件内格式必须为K=你的机器人Token，不要添加引号或多余空格，示例：

    K=ODkxNzE4Mz...（完整Token字符串）
    

• 验证Token是否被正确读取

  • 在代码中添加调试输出，确认os.getenv("K")是否获取到有效内容：

    load_dotenv()
    token = os.getenv("K")
    print("Loaded token:", token)  # 添加此行调试
    

  • 如果输出为None，说明.env未被正确加载，可指定文件路径：load_dotenv(dotenv_path="完整的.env文件路径")

• 确认Token本身的正确性

  • 复制Token时避免携带多余空格或换行符，建议直接从Discord开发者后台复制粘贴到.env
  • 确保复制的是机器人专属Token，而非OAuth2的客户端ID或密钥

• 检查依赖与环境兼容性

  • 运行pip show discord.py查看版本，若版本过旧，执行pip install --upgrade discord.py更新到稳定版
  • 确认Python 3.9与当前discord.py版本兼容

• 关于事件循环错误

  • RuntimeError: Event loop is closed是登录失败导致的衍生问题，解决Token问题后该错误会自动消失，无需单独处理
