Can't install laravel installer via composer

问题:

I'm trying to install laravel installer with the composer on my Ubuntu PC, but I get this error during the installation. `Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/installer v1.4.1 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - laravel/installer v1.4.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - Installation request for laravel/installer ^1.4 -> satisfiable by laravel/installer[v1.4.0, v1.4.1].

  To enable extensions, verify that they are enabled in those .ini files:
    - /etc/php/7.0/cli/php.ini
    - /etc/php/7.0/cli/conf.d/10-opcache.ini
    - /etc/php/7.0/cli/conf.d/10-pdo.ini
    - /etc/php/7.0/cli/conf.d/20-calendar.ini
    - /etc/php/7.0/cli/conf.d/20-ctype.ini
    - /etc/php/7.0/cli/conf.d/20-exif.ini
    - /etc/php/7.0/cli/conf.d/20-fileinfo.ini
    - /etc/php/7.0/cli/conf.d/20-ftp.ini
    - /etc/php/7.0/cli/conf.d/20-gettext.ini
    - /etc/php/7.0/cli/conf.d/20-iconv.ini
    - /etc/php/7.0/cli/conf.d/20-json.ini
    - /etc/php/7.0/cli/conf.d/20-phar.ini
    - /etc/php/7.0/cli/conf.d/20-posix.ini
    - /etc/php/7.0/cli/conf.d/20-readline.ini
    - /etc/php/7.0/cli/conf.d/20-shmop.ini
    - /etc/php/7.0/cli/conf.d/20-sockets.ini
    - /etc/php/7.0/cli/conf.d/20-sysvmsg.ini
    - /etc/php/7.0/cli/conf.d/20-sysvsem.ini
    - /etc/php/7.0/cli/conf.d/20-sysvshm.ini
    - /etc/php/7.0/cli/conf.d/20-tokenizer.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

The error appears then I use this comment:

composer global require "laravel/installer"

It says that it requires zip extension

laravel/installer v1.4.0 requires ext-zip........

Install the version respective to installed php version :

# For php v7.0
sudo apt-get install php7.0-zip

# For php v7.1
sudo apt-get install php7.1-zip

# For php v7.2
sudo apt-get install php7.2-zip

For PHP7.1 install this

sudo apt-get install php7.1-zip

On centos 7 I have used:
