ReactElement type error?

[lisp]

when i follow the installation instructions, an error occurs in npm run build:

$ npm run build

> cy-jupyterlab@0.6.0 build /Users/jamesanderson/jupyter/cy-jupyterlab
> tsc

node_modules/@types/react-transition-group/TransitionGroup.d.ts:16:30 - error TS2314: Generic type 'ReactElement<P>' requires 1 type argument(s).

16         childFactory?(child: ReactElement): ReactElement;

this, with core@4.5.0 and lab@1.0.2

[lisp]

i tried

npm install --save @types/react

which reported

+ @types/react@16.9.3

but the subsequent build failed further

(base) berlintoo:cy-jupyterlab jamesanderson$ npm run build

appears to have been rectified by

yarn remove @types/react-dom @types/react
yarn add @types/react-dom @types/react

[lisp]

in the end, there appears to be a conflict between the library and the lab version

"cy-jupyterlab@0.6.0" is not compatible with the current JupyterLab
