Unable to build JupyterLab extension if using both @jupyter-widgets/base and @jupyterlab/application

[timkpaine]

This feels like a mismatch in phosphor versions, here is an example of errors i get:

TS2322: Type 'Token<IJupyterWidgetRegistry>' is not assignable to type 'Token<any>'.
  Types have separate declarations of a private property '_tokenStructuralPropertyT'.

Types of property 'title' are incompatible.
...
Types have separate declarations of a private property '_label'.

package.json

"@jupyter-widgets/base": "^2.0.2",
"@jupyterlab/application": "^1.2.1",

This may not solve the issue, but can you try using "@jupyter-widgets/base": "^1 || ^2.0.2", at https://github.com/timkpaine/perspective/blob/a2df999ec4934101da16ff2dbd919de2956ecc22/packages/perspective-jupyterlab/package.json#L34

@jasongrout im thinking its this typo https://github.com/timkpaine/perspective/blob/a2df999ec4934101da16ff2dbd919de2956ecc22/packages/perspective-jupyterlab/src/config/plugin.config.js#L33

we only had a dep on @jupyter-widgets, so we didnt notice that the external is @jupyterlab not @jupyter

testing now

Yep, that would lead to something like this as well. Good job catching it.
