Yii2 installation using composer giving error

Question

I am trying to install Yii2 alpha. When I run the following command after downloading composer and adding

"minimum-stability": "dev"

to composer.json.

$ php composer.phar require yiisoft/yii2-framework "*"

I get the following error.

Problem 1 - The requested package minimum-stability could not be found in any version, there may be a typo in the package name.

Problem 2 - The requested package yiisoft/yii2-composer could not be found in any version, there may be a typo in the package name.

Problem 3 - The requested package yiisoft/yii2-framework could not be found in any version, there may be a typo in the package name.

Potential causes: - A typo in the package name - The package is not available in a stable-enough version according to your minimum-stability setting see https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion for more details.

Read http://getcomposer.org/doc/articles/troubleshooting.md for further common problems.

Please help me.

Answer 1

start with

php composer.phar init 

and set Minimum Stability[] to dev

then

php composer.phar require yiisoft/yii2 "*"

Answer 2

Here is working composer.json code

{
    "name": "yiisoft/yii2-app-advanced",
    ...
    "minimum-stability": "dev",
    "require": {
            "php": ">=5.4.0",
            "yiisoft/yii2": "*",
    },
    "require-dev": {
            "yiisoft/yii2-debug": "*",
            "yiisoft/yii2-gii": "*"
    },
    ...
}

Use yii2 against yii2-framework, may be you typed "minimum-stability" in the wrong place. And you don't need type yii2-composer there, it will be installed automatically
