[FIXED] Composer - the requested PHP extension mbstring is missing from your system

Issue

I've recently tried to install package through Composer, but I have got an error the requested PHP extension mbstring is missing from your system. I removed semicolon from php.ini, but it still doesn't work. What should I do?

Solution

I set the PHPRC variable and uncommented zend_extension=php_opcache.dll in php.ini and all works well.
