Eror while composer install

[dkovalenko]

I have this string in my require section in composer.json:
"jms/serializer-bundle": "0.12.0",

Running composer install results in
[RuntimeException]
Could not load package jms/serializer-bundle in http://packagist.org: [UnexpectedValueException] Could not parse version constraint ^1.0.0: Invalid ver
sion string "^1.0.0"

Your composer version might be too old. Try updating it:

composer selfupdate

Updating composer worked for me.

If the issue is solved, then please close it. :)

It worked, thank you!
