I can't install JMSSerializerBundle in symfony3.1 project

Question

I'm trying to install JMSSerializerBundle in symfony3.1 project but I get this error

command:

php ../composer.phar require jms/serializer-bundle -vvv

Using version ^2.0 for jms/serializer-bundle
[UnexpectedValueException]
Could not parse version constraint update: Invalid version string "update"

yes I did , and the solution is to add this "jms/serializer-bundle": "^2.0" in the composer.json and do update — hous

I'm not sure why you see this issue, but can you try these commands:

php ../composer.phar self-update
php ../composer.phar update
php ../composer.phar require jms/serializer-bundle

In that order. I'm thinking maybe your composer version is out of date, but not certain if that will resolve the issue. Let me know if it does.

The correct command for you based on comments would then be:

php ../composer.phar require jms/serializer-bundle "^2.0"

See if that works.
