After installing and removing vue-loader cannot compile again

ERROR in ./resources/assets/js/main.js
Module not found: Error: Can't resolve 'vue-loader' in '/home/reaper/sites/sitename'

I don't have it specifically being imported in any of these files, but get this message for most likely all my files... about 30 similar messages spammed in terminal for different files
It's not defined anywhere, so looking to git history trying to understand what else have change only thing I see is the vue-loader being added to package.json ...
might this be some sort of cache related thing ?

I am using laravel mix .

Update : So it seems that the vue-loader is present in the package.lock.json - after manually deleting it and running npm install a new package.lock.json is being generated, but it also contains the vue-loader . How this might of happen if package.json doesn't contain vue-loader anymore ?

Fixed: It was a strange cache issue:
laravel-mix pulls vue-loader as a dependency itself , so adding vue-loader to package.json , running npm install, then removing vue-loader and running npm install triggered this issue. When vue-loader was being visible in package.lock.json , but not in node_modules

Indeed, somehow laravel-mix package dependency vue-loader can't be installed after those steps you mentioned, so to fix that is a matter of uninstalling it from the project's package.json and just installing back the missing vue-loader@<version required by laravel mix's package.json> no need to use --save-dev nor --save
