As a part of Laravel 5.7 setup, I am trying to install Passport using the command:

```
composer require laravel/passport

```

But it doesn't work and gives the error:

```
Using version ^8.0 for laravel/passport
./composer.json has been updated
./composer.json has been updated
Loading composer repositories with package information

Your requirements could not be resolved to an installable set of packages.

It looks like the Passport version 8.0 is not compatible with the Version 5.7.15 of Laravel, which version is compatible here?
