通过anaconda启动jupyter notebook, terminal报错
各位大佬：小弟我用苹果电脑在terminal里升级了conda包（conda update conda）,然后通过anaconda启动jupyter notebook时，terminal却报错，报错信息如下：

麻烦大佬帮我看下这是因为什么问题导致的？该如何解决？谢谢！！！ 根据错误信息，问题可能由两个原因导致：一是 .zshrc 文件中的命令拼写错误，二是 Conda 更新后 Jupyter 相关包的版本不兼容。请按照以下步骤逐一解决：
[*] 修复 .zshrc 文件中的拼写错误：
打开终端，编辑该文件：
nano ~/.zshrc
找到第 17 行，将 Export 改为小写的 export，保存并退出（按 Ctrl+X，然后按 Y 确认，最后按 Enter）。
重新加载配置文件：
source ~/.zshrc
[*] 更新或重新安装 Jupyter 相关包：
首先，尝试更新 jupyter_server 模块：
conda install jupyter_server
如果问题仍存在，更新整个 Jupyter 环境：
conda update jupyter_core jupyter_client jupyter notebook
[*] 检查 traitlets 版本兼容性：
查看当前版本：
conda list traitlets
如果版本较旧或过新，尝试更新到最新版本：
conda update traitlets
或者回退到稳定版本（例如 5.0.5）：
conda install traitlets=5.0.5
[*] 重新安装 Jupyter Notebook：
如果上述步骤无效，可以尝试重装：
conda remove jupyter notebook -y
conda install jupyter notebook -y
[*] 创建新的 Conda 环境作为备选方案：
为避免包冲突，可以新建一个环境：
conda create -n jupyter_env python=3.8 jupyter notebook -y
conda activate jupyter_env
然后在新环境中启动 Jupyter Notebook。
完成以上步骤后，重新尝试启动 Jupyter Notebook。如果问题依旧，请提供更多错误信息以便进一步分析。
