dav*_*dev 2 php symfony composer-php
在我正在处理的 Symfony 2.7 项目中，我通过 Composer 1.6.5 使用了很多包。
几天后我无法再添加新包或重建 composer.lock。它不断耗尽内存。
当我尝试添加一个新包时，我开始注意到这个问题。但问题不在于那个包。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 ram 消耗时，它从未超过 1.5G 限制，而我的 Windows 机器仍然有足够的 ram 可用。
我注意到错误通常是在 Composer 尝试解析一个特定的包并将其写入缓存时/之后抛出的。那个特定的包确实消耗了大量内存（高达 0.5G） 一些研究告诉我这个包没有任何问题，它已经在我们的项目中，因此在 composer.json 中已经三年多了。我还在 Mac 上运行了相同的 composer install 命令，它确实设法解决了这个包并将其写入缓存，但是后来当它试图删除另一个不相关的包时它失败了，因为那时 mac 上的内存是完全消耗。
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需要我正在处理的包时，它工作得很好。
这是我的3个问题：

如果它可以帮助其他人，这是一个快速解决方案
事实证明，这是一个与 windows-xampp 相关的问题。xampp 仅支持 32 位版本的 php。这反过来意味着它始终只允许 memory_limit 为 1.5G（或 2G，其中 0.5G 分配给其他地方）。这有效地忽略了 php.ini 中的任何 memory_limit 设置或在运行时设置。
通过下载 64 位 php 并从该 64 位 php 版本运行 composer 解决了这个问题。这给了我高达 3G，足以运行作曲家
