 These errors occurs because of the file permissions. In most of the forum, I found that they suggested to give full permission 0777 for the storage folder, this can be dangerous as per the security reason.

I have added the opencart upload folders and files at /var/www/html/webocreation

Following are the commands that I run:

Change the ownership of the files and folders to the apache:apache 

sudo chown apache:apache -R . 

Let's make the all files secure by giving permissions of 0644 

find . -type f -exec chmod 0644 {} \; 

 Likewise, let's make the directory accessible for the apache 

find . -type d -exec chmod 0755 {} \;

 Now, let give access to read all files for the httpd server 

sudo chcon -t httpd_sys_content_t . -R 

 Allow write only to specific dirs 

sudo chcon -t httpd_sys_rw_content_t ./system/storage/cache -R 
sudo chcon -t httpd_sys_rw_content_t ./system/storage/download -R 
sudo chcon -t httpd_sys_rw_content_t ./system/storage/logs -R
sudo chcon -t httpd_sys_rw_content_t ./system/storage/modification -R 
sudo chcon -t httpd_sys_rw_content_t ./system/storage/session -R 
sudo chcon -t httpd_sys_rw_content_t ./system/storage/upload -R 
sudo chcon -t httpd_sys_rw_content_t ./system/storage/vendor -R

Once these commands are run then you are ready to install.

Then, open the browser and run the URL and you may get warning saying config.php file need to be writable, then for that run following two commands:

sudo chcon -t httpd_sys_rw_content_t ./config.php -R 
sudo chcon -t httpd_sys_rw_content_t ./admin/config.php -R

-----------------

Solution: The solution is just adding the right path, for the key pair that you downloaded. I was in the right folder and I gave the path by just adding "./"

ssh ec2-user@54.89.86.26 -i ./ec2-keypair.pem

then the solution is: Open the file .../vendor/scss.inc.php and go to line as given in the above case it is 1753 where you will see code like below:

foreach ($args as $arg) {

    list($key, $value) = $arg;

    $key = $key[1];

    if (empty($key)) {

        $posArgs[] = $value;

    } else {

        $keyArgs[$key] = $value;

    }

}

Then change the line to the following, the changes done is in bold. 

foreach ($args as $arg) {

    list($key, $value) = $arg;

    if (!empty($key[1])) {

        $key = $key[1];

    }

    if (empty($key)) {

        $posArgs[] = $value;

    } else {

        $keyArgs[$key] = $value;

    }

}
