总结

Configuring a Jupyter Server — Jupyter Server documentation

By default, Jupyter Server looks for server-specific configuration in a jupyter_server_config file located on a Jupyter path. To list the paths where Jupyter Server will look, run:

https://jupyter-server.readthedocs.io/en/latest/users/configuration.html

jupyter lab --generate-config

会在用户目录~/.jupyter/下生成文件jupyter_lab_config.py，对其进行修改，涉及以下部分：

遇到的问题-snippet无法正常安装使用

问题现象说明

无法保存，或者无法写code部分。

解决过程

换老版本的 jupyter lab

我查了一下,jupyter lab==4 版本异常， version3 正常，最新的version3 版本如下：

pip install --user jupyterlab==3.6.7

总结

遗留问题&思考

win server 上面的jupyter lab 也可以通过同样方式解决吧？

似乎不对, 后面升级到 3.6.7 试试。

UPDATE # 2024-02-09T02:42:57+0800

发现还有 bug: 无法保存.

最终发现作者弃坑了

只能用这个替代. https://github.com/elyra-ai/elyra?tab=readme-ov-file

注意坑点 1 `Permission denied: '/usr/etc/jupyter/jupyter_server_config.d/elyra.json’`

要用 root 执行如下命令或者指定安装时 —user 安装到用户路径下.

/usr/etc # chmod -R 777 jupyter

否则,运行 jupyter server extension enable elyra 时报错:

Permission denied: '/usr/etc/jupyter/jupyter_server_config.d/elyra.json’

坑点 2 运行报如下错误`JupyterLab application assets not found in "/home/jupyterlab/.local/share/jupyter/lab”`

解决方案, 一般是抄模版, 这个路径里面用户名不对应导致.

在jupyter_lab_config.py 把/home/jupyterlab/.local/share/jupyter/lab 配置到c.LabApp.app_dir 即可.

Here is permanently fixing solution. Runjupyter lab --generate-config. Then config file is created with printing location of the file(eg. Writing default config to: /Users/blabla/.jupyter/jupyter_lab_config.py). Open the config file and modify content into c.LabApp.app_dir = '/opt/homebrew/share/jupyter/lab'. That's all. @LukaBradeško

坑点 3. 存 snippet 时 `string index out of range`

display name 首字母一定是罗马字符, 不能是中文

4. code snippet 操作说明

Exporting code snippets

To export code snippets:

$ elyra-metadata export code-snippets \ --directory "/tmp/foo"

The above example will export all code snippets to the “/tmp/foo/code-snippets” directory.

Note that you must specify the --directory option.

There are two flags that can be specified when exporting code snippets:

To include invalid code snippets, use the -include-invalid flag.

To clean out the export directory, use the -clean flag. Using the -clean flag in the above example will empty the “/tmp/foo/code-snippets” directory before exporting the code snippets.

Importing code snippets

To import code snippets:

$ elyra-metadata import code-snippets \ --directory "/tmp/foo"

The above example will import all valid code snippets in the “/tmp/foo” directory (files present in any sub-directories will be ignored).

Note that you must specify the --directory option.

By default, metadata will not be imported if a code snippet instance with the same name already exists. The --overwrite flag can be used to override this default behavior and to replace any installed metadata with the newer file in the import directory.
