Question

I am trying to install the yii framework. I already had a composer installed. so i run the command to install composer assset plugin:

php composer.phar global require "fxp/composer-asset-plugin:~1.1.1"

the command runs for sometimes and gives an error:

Fatal error:Call to undefined method composer\\package\\Loader\\ArrayLoader::praseLinks<>

but, new project is created with:

php composer.phar create-project yiisoft/yii2-app-basic basic 2.0.8

Answer 1

Try this

php composer.phar update

or else

php composer.phar self-update

Answer 2

Composer version is old. You will need to update composer. Run the following command -

php composer.phar self-update

This should resolve the error
