Stuck at resolving packages

[domoritz]

I've been waiting for 10 minutes now to resolve the extension package. Is anyone else seeing this issue?

jupyter 4.4.0
Node v11.1.0
on MacOS

> jupyter labextension install @jupyterlab/vega3-extension                                                          > /usr/local/bin/npm pack @jupyterlab/vega3-extension

Hmm, it fixed itself with an updated of jupyerlab.
