[Neos] Switching to Neos dev-master: Your requirements could not be resolved to an installable set of packages.

[Christian Glass]

Hi folks!

when editing my composer.json to switch to dev-master like this

[...]
         "typo3/neos": "dev-master",
         "typo3/neos-nodetypes": "dev-master",
         "typo3/neosdemotypo3org": "dev-master",
         "typo3/neos-kickstarter": "dev-master",
[...]


I get this error:

###############################################
user at server:~/TYPO3-Neos-1.2$ php ../composer.phar update
Loading composer repositories with package information                  
                               Updating dependencies (including 
require-dev)         Your requirements could not be resolved to an 
installable set of packages.

   Problem 1
     - Installation request for typo3/neosdemotypo3org dev-master -> 
satisfiable by typo3/neosdemotypo3org[dev-master].
     - typo3/neosdemotypo3org dev-master requires typo3/neos-seo 
dev-master -> no matching package found.

Potential causes:
  - A typo in the package name
  - The package is not available in a stable-enough version according to 
your minimum-stability setting

for more details.

misleading.



What about the note that
   dev-master
would be depending on
   typo3/neos-seo dev-master
?


This page

https://packagist.org/packages/typo3/neos-base-distribution

does not list
   typo3/neos-seo
in the "Requires" section.


Also: Is the shipping composer.json missing a line for typo3/neos-seo 
here?
