warning css-loader > cssnano > autoprefixer > browserslist@1.7.7:
Browserslist 2 could fail on reading Browserslist >3.0 config used in
other tools.

.. SNIP...

warning "@jupyterlab/vdom-extension >

"react@^15.6.1".

.. SNIP...

warning Your current version of Yarn is out of date. The latest version is "1.12.3", while you're on "1.9.4".1




Installed Jupyter Lab extension as per the official docs.



jupyter labextension install @jupyter-widgets/jupyterlab-manager



Should I worry about these ? (for working with Jupyter Lab) and I don't even have Yarn installed. I use Minoconda and using conda-forge channel



NOTE: Nodejs is installed in the primary environment while these warning came when I was installing Jupyter Lab Extensions in an environment named geospatial, and geospatial does not have Nodejs. Both don't have Yarn.

          I think it had something to with the version of npm which was pulling some unstable version of yarn. There has been few problems with npm registry recently:



          https://en.wikipedia.org/wiki/Npm_(software)#Notable_breakages



          I waited for few months and today I removed the entire Minoconda installation. Purged all the cache and config directories and files in my $HOME too.



          Then purged all files and directories related to npm and nodejs in my $HOME. Removed them from my Arch Linux. Updated Arch and then installed nodejs and npm .



          last, did a fresh installation of Miniconda then installed ipywidgets and everything worked fine.
