Jupyter Notebook启动报错：ModuleNotFoundError及TypeError求助

运行Jupyter Notebook时触发以下错误：

Traceback (most recent call last):
File "C:\ProgramData\anaconda3\Lib\site-packages\notebook\traittypes.py", line 235, in _resolve_classes
klass = self._resolve_string(klass)
^^^^^^^^^^^^^^^^^^^^^^^^^^^

ModuleNotFoundError: No module named 'jupyter_server.contents'

During handling of the above exception, another exception occurred:

TypeError: warn() missing 1 required keyword-only argument: 'stacklevel'

已尝试安装/卸载相关组件，但问题未解决。

解决步骤： #

• 安装缺失的jupyter-server组件
  执行命令安装：

  pip install jupyter-server
  

  若使用conda环境，改用：

  conda install jupyter-server
  

• 修复traitlets版本兼容性问题
  错误中的TypeError是因为高版本traitlets要求warn()必须传入stacklevel参数，但旧版本notebook未适配该要求。二选一执行：

  1. 降级traitlets到兼容版本：

     pip install traitlets==5.9.0
     

  2. 升级notebook到最新兼容版本：

     pip install --upgrade notebook
     

• 解决多Python环境路径冲突
  从错误路径看，系统同时存在Anaconda全局环境和用户目录下的Python 3.11环境，导致包版本混乱。建议创建独立conda环境隔离依赖：

  conda create -n jupyter_env python=3.10
  conda activate jupyter_env
  conda install notebook jupyter-server
  

  之后在该环境中启动Jupyter Notebook。

• 重置Jupyter配置
  若配置文件损坏，执行以下命令生成新配置：

  jupyter notebook --generate-config
  

  备份旧配置文件后，使用新配置启动。
