laravel install error ... 这是个神马问题, 太吃惊了

PATH: /vendor/laravel/framework/src/Illuminate/Foundation/helpers.php on line 476
function event(...$args)
{
return app('events')->fire(...$args);
}

PHP Parse error: syntax error, unexpected '.', expecting '&' or variable (T_VARIABLE)

先window 本地 生产代码, 然后推到git服务器. linux项目在git服务器拉下来代码, 就报了如上的错误

操作步骤 :

window
git clone
composer global require "laravel/installer"
laravel new
git add .

git commit
git push

linux
git pull
