How to install composer via ssh?

Question

SSH

My problem is that I can't download the composer using this documentation https://packagist.org. Created a composer.json file in the root folder and threw it into the file

{
    "require": {
        "vendor/package": "1.3.2",
        "vendor/package2": "1.*",
        "vendor/package3": "^2.0.3"
    }
}

And on the command line I wrote this code curl -sS https://getcomposer.org/installer | php
And got curl in response: (23) Failed writing body (0 != 16133)
