[5.4] syntax error, unexpected ':', expecting ';' or '{'

[andrey-helldar]

• Laravel Version: 5.4.36
• PHP Version: 5.6.32 (Homestead)

Description:

The project works under PHP5.6. After updating the dependencies, an error occurred:

Steps To Reproduce:

The error occurs if I access the apiResource method in api.php:

app('router')
    ->apiResource('orders', 'Api\OrdersController', [
        'only' => ['show', 'store'],
    ]);

If you remove the use of this method, the error disappears.

Next, in the file composer.lock found the following dependencies:

"name": "doctrine/annotations",
"version": "v1.6.0",
"php": "^7.1"

"name": "doctrine/collections",
"version": "v1.5.0",
"php": "^7.1"

"name": "doctrine/inflector",
"version": "v1.3.0",
"php": "^7.1"

"name": "doctrine/instantiator",
"version": "1.1.0",
"php": "^7.1"

"name": "symfony/css-selector",
"version": "v4.0.3",
"php": "^7.1.3"

"name": "symfony/event-dispatcher",
"version": "v4.0.3",
"php": "^7.1.3"

"name": "symfony/yaml",
"version": "v4.0.3",
"php": "^7.1.3"

"name": "phpdocumentor/reflection-docblock",
"version": "4.2.0",
"php": "^7.0",

"name": "phpunit/php-token-stream",
"version": "2.0.2",
"php": "^7.0"

If I use routes:

app('router')
    ->get('orders/{orders}', 'Api\OrdersController@show')
    ->name('orders::show');

app('router')->post('orders', 'Api\OrdersController@store')
    ->name('orders::store');

then problem not found.

The problem occurs because when you execute the composer update command, it runs from under php 7.2, which is set by default in Homestead.

    "require": {
        "php": ">=5.6.4",
        "andrey-helldar/spammers": "^1.0",
        "doctrine/dbal": "2.5.*",
        "graham-campbell/exceptions": "^9.0",
        "jenssegers/agent": "^2.6",
        "laracasts/utilities": "^3.0",
        "laravel/framework": "5.4.*",
        "laravel/tinker": "~1.0",
        "morrislaptop/laravel-queue-clear": "^1.1",
        "pda/pheanstalk": "^3.1",
        "predis/predis": "^1.1"
    },
    "require-dev": {
        "barryvdh/laravel-debugbar": "~2.4",
        "barryvdh/laravel-ide-helper": "^2.4",
        "filp/whoops": "^2.1",
        "fzaninotto/faker": "~1.4",
        "mnabialek/laravel-sql-logger": "^1.1",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~5.7",
        "reliese/laravel": "^0.0.13"
    },

Just found a solution to the problem in Homestead:

cd ~/code/mysite.loc/
wget https://getcomposer.org/composer.phar
cd /etc
php5.6 ~/code/mysite.loc/composer.phar update -d "/home/vagrant/code/mysite.loc/"

When executing the command, the packages successfully downgraded:
