install jui lib returns error

Hi, I can’t install Jui lib.

This is the error which I was faced .

I don’t know if this will solve the issue, but have you run:

composer.phar global require "fxp/composer-asset-plugin:^1.2.0"

it only needs to be run once, when you first install yii - or when I upgrade Yii, I usually go here:

to check to see if the version number in that command has changed (next upgrade it might be:

composer.phar global require "fxp/composer-asset-plugin:^1.3.0")

this will install any css/js packages that are required by the JUI.

Thank you so much .
