修改 Jupyter 主目录的问题

Question

有一次我将我的 Jupyter 主目录设置为 ~/Dropbox 不幸的是，由于 Dropbox 更改其文件夹名称的方式，该位置现在是我机器上指向隐藏目录的符号链接。这会导致 Jupyter 出现以下错误

Refusing to serve hidden directory '/Users/alex/Dropbox', via 404 Error

很好......我现在想更改我的 Jupyter 主目录，但我遇到的问题是我无法弄清楚它当前的设置位置。

我已经检查了我的~/.jupyter/jupyter_notebook_config.py，但这似乎与默认设置没有任何关系。

$jupyter --paths 的输出是：

config:
    /Users/alex/.jupyter
    /usr/local/Cellar/python@2/2.7.14_3/Frameworks/Python.framework/Versions/2.7/etc/jupyter
    /usr/local/etc/jupyter
    /etc/jupyter
data:
    /Users/alex/Library/Jupyter
    /usr/local/Cellar/python@2/2.7.14_3/Frameworks/Python.framework/Versions/2.7/share/jupyter
    /usr/local/share/jupyter
    /usr/share/jupyter
runtime:
    /Users/alex/Library/Jupyter/runtime

有趣的是，以下目录不存在。

/usr/local/Cellar/python@2/2.7.14_3/Frameworks/Python.framework/Versions/2.7/etc/jupyter
/usr/local/etc/jupyter
/etc/jupyter

在/Users/alex/.jupyter/jupyter_notebook_config.py 中设置c.NotebookApp.notebook_dir = '/Users/alex/' 似乎没有效果。

可以从哪里设置 Jupyter 主目录？

Answer 1

这是jupyter notebook 到throw a 404 when starting it from a hidden folder 的预期行为。

通常，jupyter notebook 将在您调用 jupyter notebook 命令的文件夹中启动。所以cd 进入你希望它运行的目录，并在那里发出jupyter notebook。

如果这不起作用，您可以尝试使用jupyter notebook --notebook-dir=NEWDIR 之类的命令行参数强制目录。

否则，您会在上面提到一个全局配置和一个本地（每个用户）配置。如果本地是默认值，那么您可能之前更改了全局配置。如果您将 ~/.jupyter/jupyter_notebook_config.py 中的本地配置更改为应该覆盖全局配置的新值。

要清理全局配置，请在 Unix 上的 /etc/jupyter 或 /usr/local/etc/jupyter/ 或 Windows 上的 %PROGRAMDATA%\jupyter\ 中查找它。

您可以列出与命令jupyter --paths 一起使用的当前配置路径。更多信息在manual。
