我尝试在 Ubuntu PC 上使用 Composer 安装 laravel 安装程序，但在安装过程中出现此错误。 `您的要求无法解决为一组可安装的软件包。
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.

然后出现错误，然后我使用此评论：
composer global require "laravel/installer"
它说它需要邮政编码扩展
laravel/installer v1.4.0 需要 ext-zip...
使用安装（安装默认版本）：
sudo apt install php-zip
或者，如果您运行的是特定版本的 PHP：
# 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 php v7.3
sudo apt-get install php7.3-zip
# For php v7.4
sudo apt-get install php7.4-zip
