由于symfony/finder，更新Symfony 2失败并显示错误

Question

执行了Symfony的标准安装，并尝试使用composer update进行更新，这给出了以下错误：

加载包含包信息的作曲家存储库更新依赖项（包括需求开发）您的要求无法解析为一组可安装的软件包。

Problem 1
 - symfony/framework-bundle v2.7.9 requires symfony/finder ~2.0,>=2.0.5 -> no matching package found.
 - symfony/framework-bundle v2.7.8 requires symfony/finder ~2.0,>=2.0.5 -> no matching package found.
 - symfony/framework-bundle v2.7.10 requires symfony/finder ~2.0,>=2.0.5 -> no matching package found.
 - symfony/framework-bundle v2.3.38 requires symfony/finder ~2.0,>=2.0.5 -> no matching package found.
 - symfony/framework-bundle v2.3.37 requires symfony/finder ~2.0,>=2.0.5 -> no matching package found.
 - symfony/framework-bundle v2.3.36 requires symfony/finder ~2.0,>=2.0.5 -> no matching package found.
 - Conclusion: remove symfony/symfony v3.0.3
 - Conclusion: don't install symfony/symfony v3.0.3

我无法添加任何其他库，因为标准更新已经失败。任何帮助不胜感激！

我无法重现您的错误 - 更新在新的symfony标准项目上工作正常

这是在呼叫composer create-project symfony/framework-standard-edition后composer update的结果

你能做什么？

尝试清除作曲家缓存

composer clear-cache
