Php composer安装持续消耗所有RAM内存

在我正在进行的Symfony 2.7项目中，我通过Composer 1.6.5使用了很多软件包

因为几天之后，我无法再添加新包或重建composer.lock。它的内存一直不足

当我尝试添加一个新包时，我开始注意到这个问题。但问题不在于这个方案。因为作为测试，我现在正试图通过删除composer.lock文件并执行以下命令来重建composer.lock：

php -d memory_limit=-1 C:/ProgramData/ComposerSetup/bin/composer.phar install -vvv

当我在运行该命令时跟踪我的ram消耗时，它永远不会超过1.5G限制，而我的Windows机器仍然有大量可用ram

我注意到，当composer尝试解析一个特定的包并将其写入缓存时，通常会抛出错误。一个特定的软件包确实会消耗大量内存（高达0.5G）。一些研究告诉我，这个软件包没有问题，它已经在我们的项目中使用了三年多了&因此在composer.json中使用了三年多。我还在Mac上运行了相同的composer install命令，它确实解决了这个包并将其写入缓存，但后来它尝试删除另一个不相关的包时失败了，因为那时Mac上的内存已完全消耗

这是我得到的错误：

奇怪的是，直到几天前，当一位作曲家要求我制作一个软件包时，它还可以正常工作

以下是我的三个问题：

为什么作曲家要消耗这么多内存

为什么composer忽略我的内存限制=-1设置，拒绝使用超过1.5G的内存

我在某个地方读到，我可以为composer配置交换空间。这是一种选择吗

以下是我的composer.json文件：

事实证明，这是一个与windows xampp相关的问题。xampp只支持32位版本的php。这意味着它只允许在任何时候将内存限制为1.5G（或2G，其中0.5G分配到其他位置）。这实际上会忽略php.ini中或运行时设置的任何内存限制

通过下载一个64位php并运行64位php版本的composer解决了这个问题。这给了我高达3G的空间，足以运行composer
composer。composer确实使用了大量内存…您的例外情况是内存限制约为268MB，因此内存限制似乎失败。您是否尝试设置一个高RAM值而不是-1e 4G？Composer真的很饿…同时，在更大的项目上至少2GB对我来说也是正常的…我已经尝试将其显式设置为-1、1G、2G和3G。当使用任务管理器跟踪ram消耗时，它（php）当它达到1.5G时总是会被杀死。异常是指尝试分配x个字节。我认为，这不是内存限制，这正是sustem试图释放的内容，或者说。php CLI的php.ini是否可能覆盖您的内存设置？不能确定，但我的php.ini（XAMPP）也设置为-1。此外，到目前为止，我们尝试在4台计算机上运行相同的composer安装命令，每台计算机都有（稍微）不同的PHP.ini和PHPStorm设置）。其中一个是使用docker容器进行项目的MAC。一台PC有32G RAM，在我运行命令时仅使用35%。它总是导致内存不足，并且总是在1.5G时终止PHP。1.5G限制说明了composer的内部内存限制。请参见此处
