Composer global require "laravel/installer" failed

Question

I shifted from windows to xubuntu. I am using Laravel in windows and installed it via composer from the docs. Everything works fine there.

But when I shifted to xubuntu installed lamp php and mysql now everything works fine including the phpmyadmin.

I also installed composer and now trying to install laravel and this error shows up below.

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 your .ini files:

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

Installation failed, deleting ./composer.json.

I tried restarting my apache2 but still the same error for me.

here is the list of my config file when I typed php --ini

Appreciate if someone can help. Thanks in advance.

Answer 1

Well, your problem is in the ext-zip extension. You open a terminal and type the following:

sudo apt install php7-zip.

See if it works out right there. OK ps. I'm sorry for my english
