Symfony2问题与作曲家安装包

Question

我正在使用Symfony2，我试图安装此软件包“troydavisson/phrets”，但仍然遇到此错误。我从来没有经历过这样的事情，所以我不知道该怎么做。我如何解决这个问题？

在“结论”中，它说“结论：删除guzzlehttp/guzzle 6.2.1”，但我甚至不显示它的安装。也许我在这里错过了些什么

我运行此命令

php -d memory_limit=-1 composer.phar require troydavisson/phrets

Answer 1

你有2个Guzzel版本之间有冲突中使用。 Composer已经安装了Guzzel，可能它需要从另一个PHP库中获取。这给自动装载机带来了问题。

如果你专注于错误，您可以看到：

只能安装一个：guzzlehttp /狂饮

troydavisson/phrets被要求Guzzel的特定版本。要解决这个问题，你必须弄清楚哪个库正在使用Guzzel，如果你不需要它删除它或更新它。如果这不能解决你的问题，你必须fork troydavisson/phrets更新并解决版本之间的冲突（确保你使用的是相同的）。如果它变得有点复杂，只需选择或找到另一种选择。
