composer install报错之it could not be found in any version

在一些接近最新版本的composer依赖包安装中，会出现如下错误。

Problem 1
    - Root composer.json requires fideloper/proxy, it could not be found in any version, there may be a typo in the package name.
  Problem 2
    - Root composer.json requires laravel/framework, it could not be found in any version, there may be a typo in the package name.
  Problem 3
    - Root composer.json requires laravel/tinker, it could not be found in any version, there may be a typo in the package name.

不管你是用在哪个项目中，如果是报这个错误，先检查一下自己的包来源地址吧，毕竟拉来别人的开源项目

执行命令： composer config -g repo.packagist composer https://packagist.org
