Try the following:

add_action( 'woocommerce_before_calculate_totals', 'auto_apply_coupon_conditionally', 10, 1 );
function auto_apply_coupon_conditionally( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    $coupon_code = 'summer'; // HERE set the coupon code (in lowercase)
    $applied     = in_array( $coupon_code, $cart->get_applied_coupons() ) ? true : false;
    $item_count  = sizeof( $cart->get_cart() );
    $total_item  = 0;

    // Remove coupon
    if ( $item_count < 2 && $applied ) {
        $cart->remove_coupon( $coupon_code );
        wc_clear_notices();
        wc_add_notice( __('You have only 1 item in cart'), 'error');
    }
    // Add coupon
    elseif ( $item_count >= 2 && ! $applied ) {
        $cart->apply_coupon( $coupon_code );
        wc_clear_notices();
        wc_add_notice( __('A coupon has been added'), 'notice' );
    }
}

Code goes in function.php file of your active child theme (or active theme). Tested and works

thanks for the code, but problem is when I am puting my coupon at coupon field, and cart have only 1 item, and the coupon been applied and showed me default success message can say me what is wrong? – mdkamrul Mar 27 '19 at 05:08
@mdkamrul This code is not made to add manually a coupon… It make it alone by himself … It AUTO APPLY or AUTO REMOVE a coupon code. (I have changed the hook back to `woocommerce_before_calculate_totals`)… For me the code works perfectly on my test server. – LoicTheAztec Mar 27 '19 at 05:21
sorry for the misunderstanding. But i need manual actually not auto. can you please give a soluton for this? – mdkamrul Mar 27 '19 at 05:36
Actually this was for manual coupon apply not auto. also I have changed the action like you said woocommerce_before_calculate_totals but no change, this working as before. can you change you code please? – mdkamrul Mar 27 '19 at 06:20
