Jupyter Notebook：nbconvert 模板本地化问题

如何解决Jupyter Notebook：nbconvert 模板本地化问题

在 conda 环境中使用 jupyter 服务器期间，我遇到了 nbconvert 模板本地化问题。 jupyter 服务器正在 /usr/local/share/jupyter/nbconvert/templates 中寻找这些，但当前不存在此本地化（可能已经存在过一次）。 为什么他不在 ~/.conda/pkgs/nbconvert-6.0.7-py37_0/share/jupyter/nbconvert/templates/ 中寻找这些，因为他应该与 env 隔离？。我不知道此路径存储在哪里以及如何解决此问题... 作为回报，每当我想打开任何 500: Internal Server Error 文件时，我都会得到 .ipynb。

对应输出：
