Laravel:您的要求无法解析为可安装的软件包集

Question

我试图在本地系统中安装Laravel,我收到错误.

操作系统:ubuntu 12.04 LTS

网络服务器:Nginx

PHP:PHP 5.3.10

步骤1 :

$ git clone https://github.com/laravel/laravel.git my_project

第2步 :

my_project$ composer install

我收到了以下错误.

Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/framework v4.2.1 requires php >=5.4.0 -> no matching package found.
    - laravel/framework v4.2.0 requires php >=5.4.0 -> no matching package found.
    - Installation request for laravel/framework 4.2.* -> satisfiable by laravel/framework[v4.2.0, v4.2.1].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

打开composer.json文件并将框架版本更改为以下内容:
