yii2 composer update error: Invalid version string "2.*"

Question

I'm use composer update in a Yii2 project, but it is exiting with an exception. I have updated composer to the lastest version, c6cc6dd6070871f4b198ed39f76dd8047c116b02, but it still doesn't work:

I don't think this is my mistake, but how do I fix the exception?

Answer 1

Michael Nguyen's answer did not work for me, but updating to dev-master did:

php composer.phar global require "fxp/composer-asset-plugin:dev-master"

One may also need to update composer itself:

php composer.phar self-update

Also there was an extensive discussion on this yesterday: link.

UPDATE. It seems to me at this moment "fxp/composer-asset-plugin:1.0.*@dev" is better again.

Answer 2

I have the same issue and discussed on Yii Forum. It seems like this is a bug with "fxp/composer-asset-plugin".

Try

php composer.phar global require "fxp/composer-asset-plugin:1.0.1"

Then do whatever you need with composer

The bug is discussed at https://github.com/francoispluchino/composer-asset-plugin/issues/129

Answer 3

It helped for me

composer self-update
composer global update
