Install from github raises ValueError: Missing extension module "lib/index.js"

I ran jupyter labextension install --debug https://github.com/lckr/jupyterlab-variableInspector from the README.

Full Output:

Errored, use --debug for full output:
ValueError: "https://github.com/lckr/jupyterlab-variableInspector" is not a valid extension:
Missing extension module "lib/index.js"

I noticed the repo has no lib/index.js but it does have src/index.ts, could it be as simple as changing the path to this file in package.json?

Hey all, I just published the current version of this extension on npm and verified that the installation works for me. Additonally, I updated the readme to reflect the new installation guidelines.

Please try installing it with jupyter labextension install @lckr/jupyterlab_variableinspector and let me know if that works for you.

Best, lckr
