I have installed Magento 2.2.4 with sample data. Now I need to remove all sample data, and I found a solution from Magento DevDoc
I used command as suggested,
php bin/magento sampledata:remove
But I got this error as following,
Loading composer repositories with package information
Removal failed, reverting ./composer.json to its original content.
[Composer\Downloader\TransportException]
The 'https://repo.magento.com/packages.json' URL required authentication.
You must be using the interactive console to authenticate
What did I miss?
