Installation & Varnish Test Results failed

[amrit_talapatra]

I'm facing the following error while I'm trying to submit my extension. Can anyone please help me out with this.

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for radware-shieldsquare/connector 5.1.0 -> satisfiable by radware-shieldsquare/connector[5.1.0].
    - radware-shieldsquare/connector 5.1.0 requires ext-http * -> the requested PHP extension http is missing from your system.

  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Hii,

-> Check the composer.json file of your extension, make sure correct dependencies mentioned in require section.
Example :

{
    "name": "vendor/modulename",
    "description": "Vendor Module Name",
    "require": {
        "php": ">=5.5.9"
    },
    "type": "magento2-module",
    "version": "1.0.0",
    "license": [
        "EULA"
    ],
    "autoload": {
    "files": [ "registration.php" ],
        "psr-4": {
            "Vendor\\ModuleName\\": ""
        }
    }
}

Check the Require section and the dependencies declared there.

-> Try to run the command using the magento composer and with sudo  Or simply with sudo :

 sudo vendor/composer/composer/bin/composer require vendor/module-name

Or

 sudo composer require vendor/module-name
