How Solve Problems While Install Ui In Laravel?

I want make in my laravel project authorization. I work on Laravel Framework 6.4.1. I found that comand php artisan make:auth dosen't exist in this version of laravel. So next I have found that if I want to generate authorization I must instal ui. But when I want install ui with composer require laravel/ui --dev I had some errors and I don't know how fix it.

Using version ^1.1 for laravel/ui
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

I don't know that this is important but i have some message from npm install

audited 29161 packages in 10.918s
found 21 high severity vulnerabilities
  run `npm audit fix` to fix them, or `npm audit` for details

And when I run npm audit fix I have

up to date in 9.586s
fixed 0 of 21 vulnerabilities in 29161 scanned packages
  21 vulnerabilities required manual review and could not be updated

What is the reason of this? Or maybe how do authorization in another way?

The composer log shows the conflicting package is illuminate/html in the following lines:

• Installation request for laravel/framework (locked at v6.4.1, required as ^6.2) -> satisfiable by laravel/framework[v6.4.1].
• Installation request for illuminate/html 5.* -> satisfiable by illuminate/html[5.0.x-dev, v5.0.0].

Removing illuminate/html package should do the trick.
