I'm seeing this error in the terminal: "Could not determine jupyterlab build status without nodejs". Even when latest version of nodejs is installed on my PC.
Please guide what should I do?
I ran into a similar issue this morning and ended up here. The diagnostic message appears to be harmless:
[W 07:35:51.998 LabApp] Could not determine jupyterlab build status without nodejs
However, the way I resolved it for my configuration (Windows 10, Anaconda distribution of Python 3.7) was to download NodeJS from the source. Choose the LTS (Long Term Support) version of Node.js rather than the "Current with the latest features" edition.
Next, ensure the node executable is in the search path. On Windows, hold the Windows key and Break. Click on Advanced System Settings -> Environment Variables -> System Variables. Double click PATH to edit. Click OK until you're out.
In a new command window, run:
jupyter lab
You're looking for something like this in the output:
[I 07:16:26.721 LabApp] Node v10.15.3
