作曲家2：有哪些新功能？

Composer是PHP的依赖项管理器，大约在8年前发布，今天发布了新版本2.0。多年来，Composer已获得许多新功能，并与PHP标准保持同步。第二个版本与较旧的项目兼容，但是将带来一些更强大的新功能。在本文中，我将向您详细介绍它们。

加速与优化

此版本中的性能已得到改进。现在，它不考虑已安装的软件包，因此更新速度更快。我们还改善了内存和处理器处理能力。

如果出于某种原因您想忽略任何特定的平台要求，则可以简单地运行以下命令： composer install --ignore-platform-req php

它将跳过PHP或特定版本的要求。如果要忽略所有要求，则应使用以前版本中已经可用的命令 --ignore-platform-reqs
