Php Symfony的Composer安装/更新失败，出现302个错误

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

在过去的几个小时里我一直在尝试，所以这可能是github服务器的一个问题，它将及时消失。有人有这个问题吗？我也尝试过--更喜欢源代码，安装symfony/symfony和其他一些软件需要很长时间，然后显示：

[RuntimeException]

  symfony/src/Symfony/Component/Intl/Resources/stubs" which does not appear t  
  o be a file nor a folder

似乎这个问题是一个临时问题（我猜是在github上），资源不可用，所以它试图重新定向

---

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

我这里也有同样的问题。好吧，这可能是当前github的问题？这对你来说是一个持续的问题吗？什么时候开始的？大约一个小时前，但我可能已经两周没用过composer了。不用担心，谢谢你，我现在就把它放在这里，看看明天能不能修好。是的。我想现在不是回到我的工作的好时机，我这里也有同样的问题。好吧，这可能是当前github的问题吧？这对你来说是一个持续的问题吗？什么时候开始的？大约一个小时前，但我可能已经两周没用过composer了。不用担心，谢谢你，我现在就把它放在这里，看看明天能不能修好。是的。我想现在不是回到我的生活的好时机
