在我正在开发的 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。它总是内存不足。
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。因为作为测试，我现在尝试通过删除该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 计算机仍然有足够的可用内存。
我注意到，当作曲家尝试解析一个特定的包并将其写入缓存时/之后，通常会引发该错误。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上运行相同的composer安装命令，它确实设法解析了这个包并将其写入缓存，但后来当它尝试删除另一个不相关的包时失败了，因为那时Mac上的内存已经满了完全消耗。
这是我得到的错误：

奇怪的是，直到几天前，当一个使用作曲家需要我正在开发的一个包时，它工作得很好。
这是我的 3 个问题：
- 为什么composer要消耗这么多内存？
- 为什么composer忽略我的memory_limit=-1设置并拒绝使用超过1.5G？
- 我在某处读到我可以为作曲家配置交换空间。这是一个选择吗？
这是我的composer.json 文件：
