I ran the command
composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition <install-directory-name>
and got the following error several times.
In RemoteFilesystem.php line 441:
The "https://repo.magento.com//packages.json" file could not be downloaded (HTTP/1.1 404 Not Found)
But while running the same command again another time, it started working fine (as can be seen in the screenshot down below)
I like to analyze what resulted in this error and how to prevent it from occurring again. Thanks for any insights!!
