Thank You for Your answers.
@FrankenBunt ,
Yes, I tried to install using composer, got same problem.

This is shared server and my hosting provider wrote “The Web server in MyDevil drives the efficient NGiNX. Additional modules enable using the “standard” .htaccess available so far only in inefficient Apache. It is possible to easily edit rewrite rules or autoindex templates”. Unfortunately my kung-fu is not strong enough and I don’t know exactly how to check it .
My clear installation is located on http://ssproblem.suriq.usermd.net/, feel free to check it.
‘Webserver configuration’ section says:
Webserver is not Apache 1.x → OK (Apache/N-G-I-N-X-htaccess-support)
If nginx does not use .htaccess like you said I don’t have any idea that I have or have not nginx 
I created a simple .htaccess file that redirects to another web address and worked, so I assume that mod_rewrite is supported correctly.
(all files were generated automatically - I did not make any changes to them)

RewriteEngine On
RewriteRule ^(.*)$ public/$1

One of the reasons NGiNX is so efficient is it does not use
