Stuck resolving packages #58

Attempting to install hub_extension and I'm stuck resolving packages (left it running for over a day and it never seems to complete)

` jupyter labextension install @jupyterlab/hub-extension

Any suggestions as to how to proceed?

This only stands a small chance of being relevant, but I had a similar issue when running jupyter lab build -- it would freeze while resolving packages with jupyterlab-hub-extension listed as the current package. I didn't figure out what was causing it, but it worked if I ran the same command as root. I had been running it as a regular user, and all of the relevant files were owned by that user, as far as I knew. It didn't make much sense to me, but like I said, there's a small chance that's relevant here.

This seems to be an issue with node 10. I was able to get it to install fine with node 8. v0.9.1 is busted in all versions of node.

So it looks like an incompatibility with yarn in particular.

jupyter lab build uses yarn, and its current version bundles yarn v1.5.1. But that version doesn't work well with Node 10. I think jupyterlab/jupyterlab#4585 is the most relevant issue. A fix (upgrading the version of yarn bundled with jupyterlab) should come with the next jupyterlab release, and for now, upgrading yarn in place is a workaround that worked for me.
