php - composer install 不断消耗所有 RAM 内存

Question

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。它一直在耗尽内存。

当我尝试添加新包时，我开始注意到这个问题。但问题不在于那个包裹。因为作为测试，我现在正尝试通过删除那个 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。

我注意到这个错误通常是在 composer 试图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)一些研究让我了解到这个包没有任何问题，它已经在我们的项目中，因此在 composer.json 中已经存在了三年多了。我还在 Mac 上运行了相同的 composer install 命令，它确实设法解析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 Composer 需要我正在处理的包时，它工作得很好。

这是我的 3 个问题:

1. 为什么 composer 消耗这么多内存？
2. 为什么 composer 忽略我的 memory_limit=-1 设置并拒绝使用超过 1.5G 的内存？
3. 我在某处读到我可以为 composer 配置交换空间。这是一个选择吗？

这是我的 composer.json 文件:

如果它可以帮助其他人，这里有一个快速的解决方案

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 到 1.5G(或 2G，其中 0.5G 分配给其他地方)。这有效地忽略了 php.ini 中或运行时设置的任何 memory_limit 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 3G，足以运行 composer
