the step i install as follow conda install -c conda-forge notebook=6. jupyterhub configurable-http-proxy nodejs nbgrader=0.8
I try to use other way, but also same issue 1 conda install -c conda-forge notebook=7* jupyterhub configurable-http-proxy nodejs nbgrader 2 conda install -c conda-forge --freeze-installed jupyter_contrib_nbextensions the second command will downgrade notebook version to 6. then sane issue
Did you look into this issue ( https://github.com/jupyter/nbgrader/issues/1794 ). It might provide some insight.

I see this Link, but didn't found solution. could you help provide more detail solution ?
And found following error. thanks in advance!

Sorry but I never found a real solution. I try with jupyterlab (so you-jupyterhub.sth/user/username/lab) but than I ran into some other issues with nbgrader, so I am not sure if this is a solution. The ananke project might include a solution (https://github.com/jeflem/ananke/tree/main), but again I can't provide more than the link.
The source of problem is that when you're using JupyterLab, the formgrader page expects to be inside an iframe, and thus changes it's click handler. When you're in the notebook, the link is a normal <a href="...">
that takes you to the assignment directory. When you're in the lab, the link uses window.parent.postMessage
to tell the outer lab frame to navigate to the assignment directory.
The issue in my opinion is two-fold:
window.parent
doesn't exist, so this link does nothing. The handler should be more aware of whether there is a parent.jupyter-notebook
. This feels too naïve to rely on for things like this.

Thanks @shreve for the details.
I agree that this test is naïve, do you have an idea how to make it more robust ?
What I don't understand is why the formgrader is served by jupyterlab if the intention is to use notebook 6.
@xinxin2v:

@xinxin2v:
- do you have jupyterlab installed ?
- is jupyter notebook working ?
- can you open formgrader from the notebook tree page ?
1 No, Only installed jupyternotebook. 2 yes, jupyter notebook working 3 yes , i can open formgrader from the notebook tree page
@brichet
What I don't understand is why the formgrader is served by jupyterlab if the intention is to use notebook 6.
@xinxin2v Reported that they're running from JupyterHub, which uses jupyter-singleuser
, which is really just jupyter-server
under the hood. This is a situation where only notebook
is installed, not jupyterlab
, but it still results in is_jlab
being true because jupyter_server's ServerApp(JupyterApp)
has name = "jupyter-server"
, even for notebook~=6 and jupyter_server~=1.
The fix is to check the environment the page is running in and use navigation that makes sense in that context. In the PR I just issued, I got rid of is_lab
in favor of more specific decision making in each of its use cases.
OK, thanks for the clarification @shreve, I didn't know that notebook < 7 ran with jupyter_server
instead of notebook_server
in some situation.
Operating system
nbgrader --version
nbgrader --version
Python version 3.9.17 (main, Jul 5 2023, 20:41:20) [GCC 11.2.0] nbgrader version 0.8.5

Expected behavior
A notebook opens upon clicking onto the name of an assignment. (formgrader page and there managing assignments) i login jupyterhub, switch to notebook, then open page of Manage Assignments , when i click on the course name in formgrader , then should open assignment folder
Actual behavior
I login jupyterhub, switch to notebook, then open page of Manage Assignments , when i click on the course name in formgrader but does nothing
Steps to reproduce the behavior
Have JupyterHub with nbgrader and one classes of ps1 setup. Go to formgrader page and there managing assignments and add an assignment or try to use the preexisting ps1 that comes with the quickstart (following the demo-setup-steps for multiple classes).
