Question

更新 - 已找到解决方案，请参阅评论，并在本 post 结尾获取更多详细信息

我在 VS Code 中使用 Jupyter Notebook，并尝试通过以下方式将我的笔记本导出到 HTML Notebook menu tab

换句话说，我正在按照 this page

的说明进行操作

我在尝试将 Jupyter Notebook 导出为 HTML 或 PDF 时遇到此错误（在“输出”的末尾）：

Jupyter command `jupyter-nbconvert` not found.

我的sys.path是：

我认为 nbconvert 包安装在：

C:\Users\EJJ\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\site-packages\nbconvert

，我发现在我的 sys.path 中倒数第三。

我的问题和这个问题有点相似：

由于与该问题的相似性，我尝试按照该线程中给出的建议进行操作。我发现通过运行以下命令导出：

python -m jupyter nbconvert --to HTML Unitled-1.ipynb

也不适用于我的安装。我没有得到 HTML 文件，而是列出了一些选项，错误消息

Jupyter command 'jupyter-nbconvert' not found

我也尝试了以下步骤：

正在卸载 nbconvert，然后以管理员身份使用 PowerShell 重新安装
正在卸载 Jupyter，然后以管理员身份使用 PowerShell 重新安装
运行以下命令：

setx PATH "%PATH%;C:\Users\EJJ\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.10_qbz5n2kfra8p0\LocalCache\local-packages\Python310\Scripts"

为了尝试提供更多关于我的安装的信息，我运行命令 python -m jupyter --version。这产生了：

Selected Jupyter core packages...
IPython          : 8.3.0
ipykernel        : 6.13.0

最后，我只是想收集一些描述相同问题的post，因为我怀疑它们没有得到解决。希望从这个问题中学到的任何知识可能有助于解决这些问题：

VSCode fails to export jupyter notebook to html

Unable to convert Jupyter Notebooks into python scripts Jupyter command `jupyter-nbconvert` not found

https://github.com/microsoft/vscode-jupyter/issues/10096（解决方法在这里，看评论）

解决方案

在 VScode 中，按 CTRL+Shift+P（默认设置）打开“命令面板”（也可在“查看”选项卡下找到）

在字段中写入Jupyter : Select interpreter to start Jupyter server

选择其他版本的python（Windows存储在我的案例中-参见）

尝试再次导出，如果 VSCode 要求，请再次同意安装 Jupyter。

Answer 1

您可以使用vscode中的导出工具将其转换为pdf。

有关详细信息，请转到此 link

Answer 2

您可以尝试使用此命令：

Jupyter : Select interpreter to start Jupyter server 并选择安装了 nbconvert 的 python 环境。

或者，您可以将 nbconvert 安装到我们运行您的笔记本所使用的环境中。应该是这个：

~\AppData\Local\Programs\Python\Python310\python.exe
