Jupyter_contrib_nbextensions: Error executing Jupyter command 'contrib'

[Time1ess]

I'm trying to install jupyter_contrib_nbextensionsFirst I install the python package with command pip3 install jupyter_contrib_nbextensions --user, it works fine.
But when I install javascript and css files with command jupyter contrib nbextension install --user, I get this errorError executing Jupyter command 'contrib': [Errno 2] No such file or directory.
I've tried to reinstall jupyter and this extension, it's still not ok.
System: macOS Sierra 10.12.4

Hmm, that's a little odd. Could you post the entire traceback of the command?

[jcb91]

PS, I take it that this isn't a conda installation, given your pip usage?

[Time1ess]

The entire traceback of the command:

$ jupyter contrib
Error executing Jupyter command 'contrib': [Errno 2] No such file or directory

Hmm, seems like the contrib command isn't on the path for some reason. Could you try a sudo updatedb, and then post the output of

sudo locate jupyter-nbextension

and then

sudo locate jupyter-contrib

it seems this may be related to issues mentioned in https://github.com/ipython-contrib/jupyter_contrib_nbextensions/issues/713#issuecomment-261663024

[Time1ess]

Yeah #713 solved my issues.

It turns out that I firstly install jupyter with sudo pip3 install jupyter, it's installed to a system path, but later I install jupyter_contrib_nbextensions with pip3 install --user jupyter_contrib_nbextensions, it's installed to ~/Library/Python/3.6/bin, but this is not included in my PATH, so this error occurs.

What I've done is uninstall all related packages about jupyter and reinstall with pip3 install --user * and update my PATH, now it works fine.

@jcb91 , Thanks.

[jcb91]

no problem, glad you got it sorted :smile:
