File ./vendor/autoload.php missing or not readable. Most likely you did not run Composer to install library files.

When I install phpmyadmin this appears. File ./vendor/autoload.php missing or not readable. Most likely you did not run Composer to install library files. I tested it on ubuntu 14.04 and 16.04 and it’s still the same thing. I installed the composer but it still continues … Can anyone help me?
