问题描述

出于某种原因，当我 pip3 一切都在这个 PATH /Users/XXX/Library/Python/3.8/bin 我的笔记本也一样。

所以我打开了我的 vscode 并转到 .zshrc 并将 export PATH=$PATH:/Users/XXX/Library/Python/3.8/bin 添加到我的路径中。

然后我去终端 jupyter notebook 我得到了 zsh: /Users/XXX/Library/Python/3.8/bin/jupyter: bad interpreter: /usr/local/bin/python3: no such file or directory

然后我返回到 .zshrc 并将路径更改为 export PATH=$PATH:/Users/XXX/Library/Python/3.8/bin/jupyter-notebook 并添加到路径中，它得到了 zsh: command not found: jupyter

我拒绝使用 conda.. 没有特别的原因。

接下来我该怎么办？

更新

我想解决上述问题的实际原因是我的 jupyter 内核在我的 VS 代码中运行良好，但无法转换为 HTML。这就是为什么我认为安装基于 Web 的 Jupyter Notebook 可以帮助我解决这个问题。显然，它没有。当我尝试在基于网络的笔记本中转换为 HTML 时，它给了我 500 Internal Error。

我也试过这样的python3 -m jupyter nbconvert --to html notebook.ipynb 我收到以下错误：

Traceback (most recent call last):

    value = obj._trait_values[self.name]
KeyError: 'template_paths'

During handling of the above exception,another exception occurred:
