- nicolab/php-ftp-client v1.5.1 requires ext-ftp * -> the requested PHP extension ftp is missing from your system.
- nicolab/php-ftp-client v1.5.0 requires ext-ftp * -> the requested PHP extension ftp is missing from your system.
- Installation request for nicolab/php-ftp-client ^1.5 -> satisfiable by nicolab/php-ftp-client[v1.5.0, v1.5.1].
To enable extensions, verify that they are enabled in your .ini files:
- C:/php-7.2.14/php.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Installation failed, reverting ./composer.json to its original content.
