- 这种情况发生在:
我要在自己的
ThinkPHP5.1.2框架中，使用composer命令安装workerMan拓展的时候所提示的信息 - composer 命令：
composer require topthink/think-worker=v2.0.9 - 提示信息
- 打印信息如下：
./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
- Can only install one of: topthink/think-installer[v2.0.0, v1.0.12].
- Can only install one of: topthink/think-installer[v2.0.0, v1.0.12].
- Can only install one of: topthink/think-installer[v2.0.0, v1.0.12].
- topthink/think-worker v2.0.9 requires topthink/think-installer ^2.0 -> satisfiable by topthink/think-installer[v2.0.0].
- Installation request for topthink/think-worker v2.0.9 -> satisfiable by topthink/think-worker[v2.0.9].
- Installation request for topthink/think-installer (locked at v1.0.12) -> satisfiable by topthink/think-installer[v1.0.12].
Installation failed, reverting ./composer.json to its original content.- 通过对提示信息的阅读理解，说明当前的框架只让安装
v2.0.0, v1.0.12的其中一个; 也就是说，当前的ThinkPHP框架太低，不足以满足v2.0.9版本的 workerMan; 解决方案就是：安装一个较低版本的 workerMan呗！
