I have been working to build the Pangeo notebooks locally, and I have noticed that the base-notebook postBuild fails, only intermittently, during the jupyter labextension install:
Building jupyterlab assets (build:prod:minimize)
An error occured.
RuntimeError: JupyterLab failed to build

But sometimes it works, sometimes it doesn't, with no changes to any of our code. It's pretty weird. I'm guessing some sort of network timeout from some server somewhere. Has anyone seen this?
