Hi,
I have problem with the server extension. When running jupyter serverextension list I get:
config dir: C:Users####.jupyter
jupyterlab_git enabled
- Validating...
Error loading server extension jupyterlab_git
X is jupyterlab_git importable?
config dir: C:Users####Anaconda3etcjupyter

jupyter_nbextensions_configurator 0.4.1 ok
I have run pip install --upgrade jupyterlab jupyterlab-git and jupyter lab build and tested several different options. Here are some logs from when launching Jupyter Lab

What is a possible solution to my issue?
I am using a Macbook with OS Sierra, and running Python 3.6.1 and Jupyter Notebook Server 5.0.0
I installed Jupyter Notebook extensions, following the instructions as mentioned on https://github.com/ipython-contrib/jupyter_contrib_nbextensions
While the notebooks work fine on my system, I cannot view the nbextensions tab. The following is the error log I see on running jupyter notebook in terminal. I have seen some related problems posted here on SO, but they seem to be about installing specific extensions.
Further, one of the solutions seemed to be suggest pip install jupyter_nbextensions_configurator, but as can be seen from the output below, I already have the extension installed.
Requirement already satisfied: traitlets in /usr/local/lib/python3.6/site-packages (from jupyter_nbextensions_configurator)

However, in the logs, you will notice that ModuleNotFoundError: No module named 'jupyter_nbextensions_configurator' is one of the error messages.

Why there is error relates to jupyterlab?
I have previous jupyter (with three kernels) on this node, would that matter?
How can I completely uninstall the existing jupyter related tool?
Thank you very much.
The text was updated successfully, but these errors were encountered:
init_server_extensions should see these extension-loading errors and move on. Are there later errors that indicate why it’s not starting?

Error output when running tests #2101
I’m seeing the following when running the Python tests:
The text was updated successfully, but these errors were encountered:
The following is my output when I run the js tests (it hangs indefinitely on the mockextension group):
Hmm, we’re importing SYSTEM_JUPYTER_PATH here, looks like we need to check if it is empty.
For the former, check that your jupyter_core is up to date. I don’t think that there should be any case where SYSTEM_JUPYTER_PATH is an empty list (unless conda packaging changes it?)
(Thomas’ answer makes more sense).
nbextensions are using the same pattern:
nbext = pjoin ( SYSTEM_JUPYTER_PATH [ 0 ], ‘nbextensions’ )
The second issue looks like a symptom of the first.
I tried pip install —upgrade jupyter-core but no luck.
I ran a conda list and I have a couple jupyter-cores:
jupyter_client 4.2.2 py35_0 jupyter_console 4.1.1 py35_0 jupyter_contrib_core 0.3.0 py35_0 conda-forge jupyter_core 4.1.0 py35_0 «>
That’s a bit disturbing that there are two different versions. Try uninstalling with both pip and conda, and then installing it again with just one.
Correction, three versions. Even worse.
Ok, I’m upgraded but still seeing the above errors:
I should mention that I’ve installed all extensions using —sys-prefix and cleared out any extension config in nbconfig and labconfig in my user directory.

Error loading server extension jupyter_nbextensions_configurator #2584
Apologies if a similar issue has been opened, but I wasn’t able to find it.
The notebook was working just fine yesterday, but now I get this error.
The effect of this error is that I cannot open new notebooks. The old notebooks work just fine.
I don’t know if this is relevant but I don’t have any extensions. I remember I installed an extension a while back but recall deleting it.
There are no files in
I’m using Linux Elementary OS Loki (based on Ubuntu16.04) 64-bit.
conda —version == 4.3.22
jupyter —version == 4.3.0
Edit: pip list shows that I’ve «widgetsnbextensions»
The text was updated successfully, but these errors were encountered:
An error loading an extension shouldn’t prevent you from creating a new notebook. 😕
The list of enabled extensions is in
Here’s the output from notebook.json
<
«load_extensions»: <
«nbextensions_configurator/config_menu/main»: true,
«collapsible_headings/main»: true
>,
«Notebook»: <
«Header»: false,
«Toolbar»: true
>
>
I’ve both deleted it and removed the lines inside load_extensions and still shows the error and prevents any new notebook. Any notebook made elsewhere is working just fine. Just no new ones.
An error loading an extension shouldn’t prevent you from creating a new notebook. 😕
I fully agree with this. It looks to me as though you have the jupyter_nbextensions_configurator serverextension enabled in config (this is in server config rather than frontend js config files, where JavaScript nbextensions are enabled, which is why the edit hasn’t fixed it for you), but you don’t have the required python package installed. In situations like this, I would expect notebook server to log the failed import as an error, but continue loading anyway. Is this not the specified behaviour? At any rate, since the extension code isn’t even present to load, it can’t be at fault directly :/
To fix this, you should hopefully be able to just run
I add the —sys-prefix flag since it’s the default for anaconda installs, but you may also want/need to run the same using the —user or —system flag instead, depending on how you enabled it in the forest place. Alternatively, you should be able to find the keys to manually remove in the jupyter_notebook_config.json (or .py ) file(s) in one or more of the config paths in the output of jupyter —paths .
Hope that makes sense? Let me know if not!
you have the jupyter_nbextensions_configurator serverextension enabled in config (this is in server config rather than frontend js config files,
Aha, thanks for spotting my mistake there.
In situations like this, I would expect notebook server to log the failed import as an error, but continue loading anyway. Is this not the specified behaviour?
That is indeed what it should be doing. I wonder if these are actually two separate issues that just happen to be showing up together.
jupyter serverextension disable —sys-prefix jupyter_nbextensions_configurator
Ran the command. Error is gone. Still can’t create new notebooks.
I don’t know if this was appearing before (most probably did) but now I’ve noticed this
404 GET /nbextensions/nbextensions_configurator/tree_tab/main.js?v=20170620173117 (127.0.0.1) 29.03ms referer=http://localhost:8888/tree
Error is gone. Still can’t create new notebooks.
Ok, my guess is that @takluyver is correct & you have another unrelated error that just happens to have shown up at the same time as the missing serverextension.
I don’t know if this was appearing before (most probably did) but now I’ve noticed this
This is another hangover from jupyter_nbextensio s_configurator, which you can get rid of by running
As before, you may also want/need to substitute the —sys-prefix flag for —system or —user . By default, the configurator also enables an nbextension with the require path nbextensions_configurator/config_menu/main , so you may also want/need to disable that one.

I’m trying to install the extensions, after reading this post , however it seems not working as it should and I keep receiving the following error:
I read several issues here and on the web and came with nothing.

At the bottom is the error dump I get every time I launch jupyter.
I was using Pycharm but decided to switch to Jupyter because that’s what the current video series I’m watching uses. Here is me trying to run the code at the beginning of said tutorial in Jupyter. I imported the libraries in that image (except struct, I have no idea what that is and can’t find it. :/) prior to installing Anaconda, so maybe it’s not finding them because it doesn’t know where they are?
Thanks for any help, and sorry for the text dump below. Things were going smooth before I decided to switch. :[

Первая часть, кажется, относится к проблемам с брандмауэром, но, похоже, в конце концов она подключится. Вторую часть я просто не понимаю.
Я пробовал переустановить Anaconda, но ошибка повторяется. Не могли бы вы сообщить мне, что мешает этому работать должным образом?
Спасибо
Я использую Macbook с ОС Sierra и запускаю Python 3.6.1 и Jupyter Notebook Server 5.0.0. Я установил расширения Jupyter Notebook, следуя инструкциям, указанным на https://github.com/ipython-contrib/jupyter_contrib_nbextensions
Хотя ноутбуки отлично работают в моей системе, я не могу просмотреть вкладку nbextensions. Ниже приведен журнал ошибок, который я вижу при запуске jupyter notebook в терминале. Я видел некоторые связанные проблемы, размещенные здесь на SO, но они, похоже, об установке определенных расширений.
Кроме того, одним из решений, казалось, было предложение pip install jupyter_nbextensions_configurator, но, как видно из приведенного ниже результата, у меня уже установлено расширение.
Requirement already satisfied: traitlets in /usr/local/lib/python3.6/site-packages (from jupyter_nbextensions_configurator)
Requirement already satisfied: tornado in /usr/local/lib/python3.6/site-packages (from jupyter_nbextensions_configurator)
Однако в журналах вы заметите, что ModuleNotFoundError: No module named 'jupyter_nbextensions_configurator' является одним из сообщений об ошибках.
