[FIXED] laravel new blog not work mockery/mockery 1.4.0

Issue

Today I wanted to create a new project with Laravel with this command

laravel new blog

But I get this error

Crafting application...
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for mockery/mockery 1.4.0 -> satisfiable by mockery/mockery[1.4.0].
    - mockery/mockery 1.4.0 requires php ^7.3.0 -> your PHP version (7.2.23) does not satisfy that requirement.

Why should php7.3 be read when Laravel himself says at least php7.2.5 ???

Solution

Run composer update.

The reason:

Your PHP version is too low. You've got 7.2.23 installed, and mockery/mockery 1.4 requires 7.3.0

The best solution is to upgrade your PHP version. Alternatively, you can reduce mockery's version to 1.3.1, which only requires PHP 5.6 or above.

My bug report can be found here

As of 2020-05-21, the zip files that laravel new ___ uses will try to install mockery/mockery version 1.4. This won't work with versions of PHP below 7.3. In order to fix this, run composer update, and mockery will be downgraded to a compatible version.
