<think>我们再次分析这个Jupyter Notebook启动日志,问题主要有两个:
1. 端口占用:Jupyter尝试使用8888、8889、8890、8891端口都失败,最终使用了8892端口。
2. 语言服务器未安装:日志中列出了多个未安装的语言服务器。
但是,注意这次启动实际上是成功的,因为它最终使用了8892端口,并给出了访问链接。所以核心问题并不是启动失败,而是:
- 需要手动复制链接访问(因为默认端口被占用,导致每次启动可能端口不同)
- 语言服务器未安装,影响代码编辑体验
因此,解决方案分为两部分:
一、解决端口占用问题,让Jupyter能稳定使用固定端口(例如默认的8888)
二、按需安装语言服务器以增强功能
具体步骤:
第一部分:解决端口占用
1. 找出占用8888端口的程序并关闭,或者让Jupyter使用其他固定端口(避免每次启动都要换端口)
方法A:关闭占用8888端口的进程(以管理员身份运行命令提示符):
netstat -ano | findstr :8888 # 查找占用8888端口的进程ID(PID)
taskkill /PID <PID> /F # 强制结束该进程
方法B:配置Jupyter使用其他固定端口(比如8889):
方法1:每次启动时指定端口:jupyter notebook --port 8889
方法2:修改默认配置文件(如果没有配置文件,先运行:jupyter notebook --generate-config):
打开生成的配置文件(位于C:\Users\Administrator\.jupyter\jupyter_notebook_config.py)
搜索并修改:c.ServerApp.port = 8889
第二部分:安装语言服务器(可选,如果需要代码补全等功能)
例如,安装Python语言服务器:
pip install python-lsp-server
安装后,重启Jupyter Notebook,它应该能自动检测到。
注意:日志中列出的其他语言服务器(如bash、dockerfile等)如果需要也可以安装,但通常只需安装自己需要的语言即可。
另外,日志中显示最终成功启动在8892端口,所以当前可以复制给出的链接(http://localhost:8892/...)在浏览器中打开使用。
但是,为了避免每次启动都要换端口,建议采用方法B(修改默认端口)为佳。
总结解决方案:
1. 关闭占用8888端口的程序,或者为Jupyter配置一个未被占用的固定端口。
2. 如果需要更好的代码编辑体验,安装所需语言的语言服务器。
如果用户希望每次启动都使用同一个端口(比如8889),那么采用修改配置文件的方式最合适。
操作步骤示例(配置固定端口):
1. 生成配置文件(如果已有则跳过):
jupyter notebook --generate-config
2. 打开配置文件(文件路径会显示在命令输出中,通常是用户目录下的.jupyter文件夹)
3. 搜索“c.ServerApp.port”,取消注释并设置端口号,例如:
c.ServerApp.port = 8889
4. 保存配置文件,下次启动就会使用8889端口。
如果8889也被占用,则再换一个。
安装语言服务器示例(安装Python语言服务器):
pip install python-lsp-server
安装后,重启Jupyter Notebook即可。
注意:在Conda环境中,使用conda安装也可以,但需要先搜索是否有对应的conda包。例如:
conda search python-lsp-server # 查看是否有conda包
conda install -c conda-forge python-lsp-server # 从conda-forge安装
因为当前环境名为cuda128,所以安装时需要确保环境激活。
最后,由于日志中显示已经成功启动,所以当前问题主要是配置优化,并非错误。</think>从日志分析,Jupyter Notebook启动时遇到两个主要问题:
### 问题分析
1. **端口冲突问题**(核心问题):
```log
[I 2025-07-11 13:18:37.756 ServerApp] The port 8888 is already in use...
[I 2025-07-11 13:18:37.757 ServerApp] The port 8889 is already in use...
```
- Jupyter尝试使用8888-8891端口均被占用
- 最终使用8892端口启动成功
- **原因**:其他Jupyter实例、开发服务器或后台程序占用了默认端口
2. **语言服务器缺失问题**(功能限制):
```log
[I 2025-07-11 13:18:37.820 ServerApp] Skipped non-installed server(s): bash-language-server, python-language-server...
```
- 缺少多种编程语言的LSP支持
- **影响**:代码补全、错误检查、函数提示等智能功能不可用
---
### 解决方案
#### 1. 解决端口冲突(永久性方案)
**方法A:修改Jupyter默认配置**
```cmd
# 生成配置文件(如果不存在)
jupyter notebook --generate-config
# 编辑配置文件
notepad C:\Users\Administrator\.jupyter\jupyter_notebook_config.py
```
找到并修改:
```python
c.ServerApp.port = 9999 # 改为可用端口
c.ServerApp.open_browser = False # 禁止自动开浏览器
```
**方法B:创建启动脚本** `start_jupyter.bat`:
```bat
@echo off
set JUPYTER_PORT=9999
jupyter notebook --port %JUPYTER_PORT% --no-browser
```
#### 2. 安装语言服务器(增强功能)
```cmd
# 安装Python语言支持
pip install python-lsp-server jupyter-lsp-python
# 安装基础语言支持包
pip install jupyterlab-lsp
```
安装后重启Jupyter,代码编辑将获得智能提示功能
#### 3. 验证解决方案
```cmd
jupyter notebook
```
检查:
- 是否直接使用配置的端口启动
- 代码编辑时是否有智能提示
---
### 预防措施
1. **端口管理**:
```cmd
# 查看端口占用
netstat -ano | findstr :8888
```
2. **使用环境隔离**:
```cmd
conda create -n jupyter_env python=3.10 jupyter jupyterlab-lsp
conda activate jupyter_env
```
3. **创建桌面快捷方式**:
目标位置:`cmd.exe /k start_jupyter.bat`
