在我正在从事的Symfony 2.7项目中，我通过Composer 1.6.5使用了很多软件包。
几天以来，我不再可以添加新软件包或重建composer.lock。它会不断耗尽内存。
当我尝试添加新软件包时，我开始注意到该问题。但是问题不在于那个包裹。因为作为测试，我现在试图通过删除该composer.lock文件并执行以下命令来重建我的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内存消耗时，它从未超过1.5G限制，而我的Windows机器仍然有大量可用的内存。
我注意到，在作曲家尝试解析一个特定的程序包并将其写入缓存时/之后，通常会引发该错误。一个特定的程序包确实会消耗大量内存（高达0.5G）。一些研究告诉我，这个程序包没有错，它已经存在于我们的项目中，并且已经存在于composer.json中已有三年多了。我还在Mac上运行了相同的composer install命令，它确实设法解决了该程序包并将其写入缓存，但是后来在尝试删除另一个不相关的程序包时失败了，因为那时Mac上的内存已被删除。完全耗尽。
这是我得到的错误：

奇怪的是，直到几天前，当一个使用过的作曲家要求我正在处理的程序包时，它还可以正常工作。
这是我的3个问题：

万一它可以帮助别人，这是一个快速解决方案
事实证明，这是Windows-xampp相关的问题。 xampp仅支持32位版本的php。这又意味着它始终始终只允许将memory_limit限制为1.5G（或将2G，其中0.5G分配给其他位置）。它实际上会忽略php.ini中的任何memory_limit设置或运行时中设置的设置。通过下载64位php并从该64位php版本运行composer来解决该问题。最多可以给我3G的声音，足以运行作曲家
