Jupyter Notebook, missing toolbar with nbextensions

问题

我正在使用Ubuntu 20.04，并在使用pipenv设置的虚拟环境中工作（Python版本为3.8）。我喜欢使用Jupyter Notebook，并决定安装nbextensions包。安装完成没有错误，我可以通过命令行激活特定扩展，但当我启动Jupyter Notebook时，我没有在启动页面上看到工具栏，可以在其中选择要启用的扩展。

我在这里找到了这个问题：https://stackoverflow.com/questions/49647705/jupyter-nbextensions-does-not-appear 并阅读了其中的内容，但其中的解决方案对我的情况没有帮助。

这是我做的事情：
（在设置了虚拟环境的正常终端中）：

  1. $ pipenv install jupyter_contrib_nbextensions
  2. $ pipenv install jupyter-nbextensions-configurator

（这两个命令似乎都成功执行）
然后在激活虚拟环境（pipenv shell）后，我运行了：

  1. $ jupyter contrib nbextension install --user
  2. $ jupyter nbextensions_configurator enable --user

这两个命令似乎也都成功执行。
我能够通过运行jupyter nbextension enable highlight_selected_word/main来启用选定单词的高亮显示。我在笔记本中进行了测试，它正常工作，但很好地拥有工具栏会更好。
我尝试运行jupyter nbextension enable nbextensions_configurator/tree_tab/main，并得到以下输出：

  1. Enabling notebook extension nbextensions_configurator/tree_tab/main...
  2.       - Validating: problems found:
  3.         - require?  X nbextensions_configurator/tree_tab/main

这是jupyter nbextension list的输出（我认为看起来可疑）：

  1. 已知的nbextensions:
  2.   配置目录: /home/my_user_name/.local/share/virtualenvs/analysis-vLcf5S6s/etc/jupyter/nbconfig

有什么想法吗？

英文:

I'm using Ubuntu 20.04 and working in a virtual environment set up with pipenv. (Python version is 3.8) I like Jupyter Notebook and decided to install the package nbextensions. Installation finished without errors, I can activate a particular extension via the command line, but when I start Jupyter Notebook I don't get a toolbar on the start page where I can just put checks on the extensions that I want to enable.

I found this question posted here: https://stackoverflow.com/questions/49647705/jupyter-nbextensions-does-not-appear and read through it, but the solutions there do not help in my case.

Here is what I did:
(in a normal terminal where I have the virtual environment set up):

  1. $ pipenv install jupyter_contrib_nbextensions
  2. $ pipenv install jupyter-nbextensions-configurator

(both commands seem to be successful)
Then after activation of the virtual environment (pipenv shell) I run

  1. $ jupyter contrib nbextension install --user
  2. $ jupyter nbextensions_configurator enable --user

Those also seem to be successful.
I was able to enable the highlighting of a selected word by running jupyter nbextension enable highlight_selected_word/main. I tested it in a notebook and it works as it should, but it would be good to have the toolbar.
I tried jupyter nbextension enable nbextensions_configurator/tree_tab/main and got the following output:

  1. Enabling notebook extension nbextensions_configurator/tree_tab/main...
  2.       - Validating: problems found:
  3.         - require?  X nbextensions_configurator/tree_tab/main

Here is the output of jupyter nbextension list (that I think looks suspicious):

  1. Known nbextensions:
  2.   config dir: /home/my_user_name/.local/share/virtualenvs/analysis-vLcf5S6s/etc/jupyter/nbconfig
  3.     notebook section

  6.         - require?  X nbextensions_configurator/config_menu/main
  7.       jupyter-js-widgets/extension  enabled 
  8.       - Validating: OK

  35.     notebook section
  36.       jupyter-js-widgets/extension  enabled 
  37.       - Validating: OK

Any ideas?

我输入了您提供的相同链接，因为我在将Ubuntu 2204用于WSL时遇到了相同的问题。有关降级到版本6.1.5的第二个答案对我有用！

在降级后，再次运行jupyter contrib nbextension install --user，打开jupyter笔记本，搞定了！

英文:

Hey I entered the same link you provided because I was having the same issue using Ubuntu 2204 into WSL. The second answer about downgrading to version 6.1.5 worked for me!

After downgrading ran jupyter contrib nbextension install --user once again, entered jupyter notebook, and done!
