Trying to install laravel/ui composer is failing

Question

I am trying to install the laravel/ui for Laravel 6.4, but when I try to install through composer I get the error message Your requirements could not be resolved to an installable set of packages.

Problem 1
    - The requested package laravel/framework (locked at v6.4.0, required as ^5.0) is satisfiable by laravel/framework[v6.4.0], but these conflict with your requirements or minimum-stability.
  Problem 2
    - laravel/framework v5.0.9 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.
...
...
...
To enable extensions, verify that they are enabled in your .ini files:
...
Installation failed, reverting ./composer.json to its original content.

I have tried to install it manually as well, but to no avail. composer.json : composer.json

Answer 1

If mcrypt or ext-mcrypt is not enabled open your php.ini and search for

;extension=php_mcrypt.so then remove the ; from the beginning of that line. Same procedure for the other extension.

source to find and open the file path; Laravel requires the Mcrypt PHP extension
