我正在尝试解决以下作曲家依赖问题，我通常理解并修复它们，但这一次，我遇到了麻烦。
这是：
vagrant@vagrant-ubuntu-trusty-64:~/www/producteev4$ composer install
Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Your requirements could not be resolved to an installable set of packages.
Problem 1
- friendsofsymfony/rest-bundle dev-master requires doctrine/inflector 1.0.* -> satisfiable by doctrine/inflector[1.0.x-dev].
- friendsofsymfony/rest-bundle dev-master requires doctrine/inflector 1.0.* -> satisfiable by doctrine/inflector[1.0.x-dev].
- Can only install one of: doctrine/inflector[1.1.x-dev, 1.0.x-dev].
- Installation request for doctrine/inflector 1.1.x-dev -> satisfiable by doctrine/inflector[1.1.x-dev].
- Installation request for friendsofsymfony/rest-bundle dev-master -> satisfiable by friendsofsymfony/rest-bundle[dev-master].
非常感谢任何帮助。
