Ubuntu22.04下Jupyter Notebook打开.ipynb文件报500错误求助

问题详情 #

• 环境：Ubuntu22.04，Anaconda创建的名为FWI的Python3.9虚拟环境
• 操作：通过conda install jupyter notebook完成Jupyter安装后，执行pip install notebook时触发错误：

  ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: '/home/master/anaconda3/envs/FWI/lib/python3.9/site-packages/pickleshare-0.7.5.dist-info/METADATA`
  

• 症状：无法打开.ipynb文件，尝试pip install --upgrade、pip install --upgrade nbconvert均无效，终端抛出核心错误：

  AttributeError: partially initialized module 'charset_normalizer' has no attribute 'md__mypyc' (most likely due to a circular import)

解决方案 #

1. 修复损坏的pickleshare包 #

pip安装失败提示pickleshare的METADATA文件缺失，先通过conda重装该包：

conda activate FWI
conda uninstall pickleshare -y && conda install pickleshare -y

2. 解决charset_normalizer循环导入问题 #

该错误是因为包文件损坏或版本冲突，通过conda重装修复：

conda uninstall charset_normalizer -y && conda install charset_normalizer -y

3. 补全bs4依赖的字符检测库 #

错误中显示bs4找不到cchardet和chardet，安装这两个包：

conda install chardet cchardet -y

4. 统一Jupyter组件的安装源 #

避免pip和conda混合安装导致的版本不一致，重装Jupyter相关组件：

conda uninstall jupyter notebook nbconvert -y && conda install jupyter notebook nbconvert -y

5. 验证修复效果 #

启动Jupyter Notebook，尝试打开目标.ipynb文件：

jupyter notebook
