bem para este caso em particular, eu apenas tive que adicionar --user ao meu comando assim:
nbgrader extension install --user
Eu não sei como, mas resolve o problema.
Eu me deparei com este erro ao tentar instalar a extensão nbgrader para o jupyterhub. O erro pode ser trivial, mas não consigo consertá-lo.

Agradecemos suas sugestões para superar esse problema.

Se você instalar nbgrader
com conda
, isso não será um problema:
$ conda install nbgrader -c conda-forge
