    要访问服务器，请在浏览器中打开此文件：
        file:///C:/Users/NETL-ris398/AppData/Roaming/jupyter/runtime/jpserver-28988-open.html
    或复制粘贴以下URL之一：
        http://localhost:8889/tree?token=4c9608e761cdbbe288c4bd627c6e4ef5c03ef28e3b7adff1
        http://127.0.0.1:8889/tree?token=4c9608e761cdbbe288c4bd627c6e4ef5c03ef28e3b7adff1

解决方案尝试 #

1. 手动访问Jupyter Server #

复制日志中提供的URL（如http://localhost:8889/tree?token=4c9608e761cdbbe288c4bd627c6e4ef5c03ef28e3b7adff1），粘贴到浏览器地址栏直接访问，确认服务器是否正常工作。

2. 强制终止Jupyter进程 #

• 打开任务管理器，找到所有名为python.exe或jupyter.exe的进程，右键选择“结束任务”
• 或在命令行执行以下命令：

  taskkill /f /im python.exe
  taskkill /f /im jupyter.exe
  

3. 重置Jupyter配置 #

执行以下命令重置Jupyter配置文件，避免配置异常导致的问题：

jupyter notebook --generate-config

然后打开生成的配置文件（路径会在命令输出中显示），找到c.ServerApp.open_browser，设置为True，确保启动时自动打开浏览器：

c.ServerApp.open</think_never_used_51bce0c785ca2f68081bfa7d91973934>

4. 禁用可疑扩展 #

日志中显示aext_assistant等Anaconda扩展加载耗时较长，尝试禁用这些扩展：

jupyter server extension disable aext_assistant
jupyter server extension disable aext_core
jupyter server extension disable aext_panels
jupyter server extension disable aext_share_notebook

之后重新启动Jupyter Notebook，观察问题是否解决。

5. 创建新的Conda环境 #

如果当前环境存在依赖冲突，创建全新的Conda环境测试：

conda create -n jupyter-test python=3.10
conda activate jupyter-test
conda install jupyter notebook
jupyter notebook
