所以我在Windows上使用symfony 2.8（Wamp 2.5，PHP 5.5.12） 我正在尝试安装FOSUserBundle 总是存在此错误：
cd myproject
composer require friendsofsymfony/user-bundle "~2.0"
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocat
e 16 bytes) in phar://C:/composer/composer.phar/src/Composer/DependencyResolver/
RuleWatchGraph.php on line 52
Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-error
s for more info on how to handle out of memory errors.
我尝试了很多解决方案，但没有一个对我有用
php -d memory_limit=-1../composer/composer.phar update
php -d memory_limit=-1 ../composer/composer.phar install
php -dmemory_limit=1G ../composer/composer.phar update --prefer-dist --no-dev
php -d memory_limit=-1 ../composer/composer.phar require friendsofsymfony/user-bundle "~2.0@dev
php composer.phar self-update .......................................
我可以使用此命令composer require friendsofsymfony/user-bundle "~2.0"安装FSOUSerBandle的唯一方法是在symfony项目之外运行它，因此它创建了一个vendor/friendsofsymfony/user-bundle文件夹
当我尝试在我的项目中复制该文件夹并创建新的捆绑包时，出现此错误
Class 'Symfony\Component\Console\Input\ArgvInput' not found in C:\p
任何人都可以帮助我！我已经在寻找解决方案已有4个小时了
