Mogens Fiebrandt Danke für deinen Tipp. Der Versuch war leider erfolglos: Hier die Fehlermeldung(en):
`./composer.json has been updated
Running composer update contentblocks/examples
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires contentblocks/examples dev-main -> satisfiable by contentblocks/examples[dev-main].
- contentblocks/examples dev-main requires typo3/cms-content-blocks 13.0.*@dev -> could not be found in any version, there may be a typo in the package name.
Potential causes:
Read https://getcomposer.org/doc/articles/troubleshooting.md for further common problems.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
