Installation Error: "NameError: name 'CoreConfig' is not defined"
Closed this issue · 8 comments
System: Ubuntu 16.04
When I run the installation
jupyter labextension install jupyterlab-spreadsheet
in my Python 3.5.2 virtualenv I get the error:
An error occured. NameError: name 'CoreConfig' is not defined See the log file for details: /tmp/jupyterlab-debug-05zbv00j.log
The log in that location outputs

Hmm... This kinda smells like a deployment issue, but I'm not sure. Can you give the output of the following commands?
jupyter troubleshoot
jupyter labextension list
That'll narrow it down a bit

I dont install any extension.
I think this is related to jupyterlab/jupyterlab#7211. @Freedomisgood, given that you've run into this installing other extensions as well, I'm inclined to believe this is towards JupyterLab core. I'll investigate some more tomorrow, and see what's up.
Solved!
That's because the version of nodejs is low..My version is v4.2.6, I thought I install the newest, but that's not true, everything is ok when i upgrade to v10.16.3
Awesome! Looking over the logs again I can see why that's the case:
subprocess.CalledProcessError: Command '['/usr/bin/nodejs', 'node-version-check.js']' returned non-zero exit status 1
Probably means the version check is using a feature not available on Node 4 (causing it to break). I'll close this for now, but @skyler14 feel free to reopen if this doesn't fix your issue.

well, I've just met the same problem with you, but I didn't solve it after upgrade the nodejs. My nodejs version is v8.10.0.
Hi you can update your nodejs to solve this problem by this simple code
conda install -c conda-forge nodejs
