通过composer安装laravel时出现此错误
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for laravel/installer ^2.1 -> satisfiable by laravel/installer[v2.1.0].
- laravel/installer v2.1.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
To enable extensions, verify that they are enabled in your .ini files:
- /etc/php/7.3/cli/php.ini
- /etc/php/7.3/cli/conf.d/10-mysqlnd.ini
- /etc/php/7.3/cli/..
..
.. You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
/etc/php/7.3/cli中没有zip.ini文件
，我尝试了这些； apt-get install php-zip得到这个结果：
php-zip is already the newest version (1:7.0+49).
The following packages were automatically installed and are no longer required:
libglade2-0 net-tools php7.0-fpm python-glade2 python-gobject python-notify python-wicd
rfkill wicd-daemon wicd-gtk
Use 'apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
和
apt-get install php7.3-zip得到以下结果：
E: Unable to locate package php7.3-zip
E: Couldn't find any package by glob 'php7.3-zip'
E: Couldn't find any package by regex 'php7.3-zip'
我查看了其他主题，但是其中任何一个都不起作用。我该如何解决这个问题
