Symfony的Composer安装/更新失败，出现302个错误

Question

我已经安装了composer并从git服务器下载了Symfony应用程序，并且在安装或更新composer时遇到了问题(同样的问题)。以下是一次更新的输出：

我在过去的几个小时里一直在尝试，所以这可能是github服务器的一个问题，很快就会消失的。有没有人遇到过这个问题？我也尝试过--首选-source，花了很长时间安装symfony/symfony和其他几个，然后显示：

[RuntimeException]

似乎这个问题是一个暂时的问题(我猜是在github上)，资源不可用，所以它正在尝试重定向。

如果将来发生这种情况，似乎最好的办法是等待几个小时(在本例中大约是3到4个小时)，看看问题是否会自行解决。
