Neos.flow📦create doesn't work

Using Neos & Flow Installation & Deployment
1

Hi community !

I cloned neos base distribution. Executed composer install, all as usual is fine.

But I can’t create new package, I always get this error:

Script Neos\Flow\Composer\InstallerScripts::postUpdateAndInstall handling the post-update-cmd event terminated with an exception

In PackageManager.php line 589:

Hi and sorry for the wait :wink:
I see that you posted the same problem here? Installation crashed (with empty package creation) · Issue #58 · neos/neos-base-distribution (github.com)

Thanks for submitting this i will look into it :wink:

Any updates on this? I get a similar error during installation (for me the neos/flow package was found more than once). The link you provided points to a post with a link pointing back to this page so that’s not very helpful.
