Version number in composer manifest of package "..." is missing or invalid¶
This happens in TYPO3 6.2 whenever an extension has a dependency on
another extension which contains a file
composer.json without any
version number (which is actually the best practice).
Simple solution for the time being since composer is not properly
supported in TYPO3 6.2 is to delete the corresponding file
composer.json or to explicitly set a version number.
