使用composer更新供应商时出现奇怪的symfony2问题

我正在工作的Symfony网站遇到了一个相当奇怪的问题。由于某种原因，当我写composer update或composer install时，我得到以下结果:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
Updating the "app/config/parameters.yml" file

我不知道为什么它说它不能在imports部分import文件-它们存在并且是可写/可读的。有人能解释一下这里发生了什么吗?
