解决方法 #

方法1：切换到官方支持的稳定分支 #

日志提示当前运行在master分支（不被支持），切换到稳定分支可解决大部分兼容问题：

1. 进入AutoGPT目录，执行：

   git checkout stable
   

2. 重新升级安装依赖：

   pip install -r requirements.txt --upgrade
   

3. 重新启动AutoGPT。

方法2：修复TTSHandler类的继承问题 #

如果不想切换分支，可手动修正TTSHandler的类定义：

1. 找到AutoGPT目录下的autogpt/tts/__init__.py文件（若路径不同，搜索包含class TTSHandler的文件）。
2. 修改类定义，确保继承自logging.Handler并调用父类初始化：

   import logging
   class TTSHandler(logging.Handler):
       def __init__(self):
           super().__init__()  # 调用父类初始化方法，继承level等属性
           # 其他原有代码保持不变
   

3. 保存文件后重新启动AutoGPT。

方法3：临时禁用TTS功能快速绕过 #

若不需要语音播报功能，可直接禁用TTS：

1. 在AutoGPT目录下找到.env文件（没有则复制.env.template重命名为.env）。
2. 添加或修改一行：

   TTS_ENABLED=False
   

3. 保存文件后重新启动AutoGPT。
