Cannot build new image

[inglesp]

Building a new image involves running jupyter lab build, but this fails with RuntimeError: npm dependencies failed to install.

Running locally, by:

• commenting out everything in the Dockerfile from RUN jupyter lab build onwards
• running docker build . --build-arg ubuntuversion=bionic --build-arg pythonversion=3.8.1
• running docker run -it --rm IMAGE_HASH bash
• running jupyter lab build inside the running container

I got the following error logs:

@inglesp in case useful, installing a later version of Node.js worked for me: Expected version ">=10". Got "8.10.0".

I could get a successful build, running ./build.sh locally, by switching out this:

datalab-jupyter/Dockerfile

Lines 16 to 17 in 92bb933

	# Required to build extensions for jupyter
	RUN apt-get install -y nodejs npm

to instead install v16 using a NodeSource PPA:

# Required to build extensions for jupyter
RUN curl -fsSL https://deb.nodesource.com/setup_16.x | bash -
RUN apt-get install -y nodejs

Note the NodeSource nodejs package contains both the node binary and npm, so no need to install npm separately.

Or any other method to install later versions e.g., Node Version Manager (NVM).
