Installation in jupyterlab dev mode

[lzfxxx]

I made some modification on original jupyterlab application, so I need to run the dev mode. I got such error after running jlpm run add:sibling ./extensions/jupyterlab-monaco(I placed the jupyterlab-monaco repo under extensions folder under jupyterlab code root directory):

$ jlpm run add:sibling ./extensions/jupyterlab-monaco
yarn run v1.3.2
$ node buildutils/lib/add-sibling.js ./extensions/jupyterlab-monaco
> jlpm run integrity
$ node buildutils/lib/ensure-repo.js

What commit are you on? Is this using the source of 0.32.1, or master?

It could be that the file-loader trick doesn't work with add:sibling (CC @saulshanabrook). It could also be that the plugin needs to be updated for whatever dev commit you are on.

@jasongrout I'm working on 0.31.1, but I've also tried add:sibling in master commit which also has the same error. I think

the file-loader trick doesn't work with add:sibling

might be the right explanation for this problem. So what should I do to resolve this problem? Maybe report this to jupyterlab main repo?
