我正在尝试将我的Laravel升级5.5为5.6.我已按照laravel网站的说明进行操作,但我收到此错误:
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package laravel/framework 5.6.* is satisfiable by laravel/framework[5.6.x-dev] but these conflict with your requirements or minimum-stability.
所以,我改变了我的composer.json文件并添加了2行:**"minimum-stability": "dev", "prefer-stable": true,**基于这个 laracast讨论的第一个答案.
一切似乎工作得很好,直到我得到另一个错误:
