Mac M1环境下Python3.11中Pyttsx3初始化报错objc未定义

问题场景 #

在Python 3.11脚本中初始化已安装的Pyttsx3模块时触发异常。执行以下代码：

import pyttsx3
engine=pyttsx3.init()

关联的nsss.py库报错：

NameError: name 'objc' is not defined. Did you mean: 'object'?

完整堆栈跟踪信息：

Traceback (most recent call last):
  File ".venv/lib/python3.10/site-packages/pyttsx3/__init__.py", line 20, in init
    eng = _activeEngines[driverName]

    o = self.data[key]()
KeyError: 'nsss'

During handling of the above exception, another exception occurred:

解决方案 #

• 安装缺失依赖：macOS平台下，Pyttsx3的nsss驱动依赖pyobjc库，执行以下命令安装：

  pip install pyobjc
  

• 虚拟环境适配：如果使用了虚拟环境，确保在对应虚拟环境中执行上述安装命令，避免依赖安装到全局环境导致无法识别。
• 版本兼容性检查：确认pyobjc版本与Python 3.11兼容，最新版pyobjc已支持Python 3.11，若安装后仍有问题，可尝试指定兼容版本：

  pip install pyobjc==9.0.1
