Node Error "unable to resolve dependency tree" while installing tailwindcss --auth - node.js

Question

I tried to install Tailwind UI Auth with php artisan ui tailwindcss --auth command. Both CSS Scaffolding and CSS auth Scaffolding were installed successfully and I ran the command npm install && npm run dev to compile the fresh scaffolding. NPM installation happend but in the dev process of the command, the app was not properly compiled. The error log as follows;

How to overcome this error? Even I updated node to latest version (v16.1.0) but coudn't fix the error...

Answer 1

The following solution worked for me;
Run the command npm audit fix --force which updates laravel-mix to 6.0.19, a SemVer major change. Then run npm run dev which will successfully compile the webpack. This error occurs due to an outdated laravel-mix package.
