背包换laravel错误安装的背包Laravel 5.3

Question

当我尝试安装，我有此错误：

# composer require backpack/base 
Using version ^0.7.3 for backpack/base 
./composer.json has been updated 
Loading composer repositories with package information 
Updating dependencies (including require-dev) 
Your requirements could not be resolved to an installable set of packages. 

    Problem 1 
    - Installation request for backpack/base ^0.7.3 -> satisfiable by backpack/base[0.7.3]. 
    - backpack/base 0.7.3 requires laravel/framework 5.3.* -> satisfiable by laravel/framework[5.3.x-dev, v5.3.0, v5.3.0-RC1, v5.3.1, v5.3.10, v5.3.11, v5.3.12, v5.3.13, v5.3.14, v5.3.15, v5.3.16, v5.3.17, v5.3.18, v5.3.19, v5.3.2, v5.3.3, v5.3.4, v5.3.5, v5.3.6, v5.3.7, v5.3.8, v5.3.9] but these conflict with your requirements or minimum-stability. 


Installation failed, reverting ./composer.json to its original content. 

如何解决呢？

Answer 1

您可能正在运行Laravel 5.2应用程序。如果是这样，你有两种选择：

1）Upgrade from Laravel 5.2 to Laravel 5.3，然后再试一次，它肯定会工作。对于一个中型项目，Laravel升级需要大约1个小时，但是使用最新最好的（Laravel和Backpack）都会带来所有好处。

2）Install Backpack for Laravel 5.2，但请注意您正在运行旧的背包版本，并且您将不会收到任何更新或新功能。

我的建议当然是选项＃1。最后，你仍然需要更新Laravel，然后更新Backpack，所以最好现在就做。
