php - 拉维尔 : Your requirements could not be resolved to an installable set of packages

Question

我正在尝试在本地系统中安装 Laravel，但出现错误。

操作系统:ubuntu 12.04 LTS

网络服务器:Nginx

PHP:PHP 5.3.10

第一步:

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

第二步:

my_project$ composer install

我遇到以下错误。

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

打开您的 composer.json 文件并将框架版本更改为以下内容:

"laravel/framework": "4.0.*"

代替

"laravel/framework": "4.2.*"
