dirty uninstall package process

[jerome-diver]

Hi and thank you for your package module.
i installed and try legit, then uninstall it.

npm r legit
npm uninstall legit

but at start server time, there is an error with legit concerned message:

webpack is watching the files...
internal/modules/cjs/loader.js:638
    throw err;

Error: cannot find module 'legit'

there is no 'legit reference code in source code, i did search with "rg" linux tool application but nothing relative to legit in my code...
Maybe the process to uninstall the package has something wrong/dirty ?
How to fix that, please ?
