在编写器中，为什么某些依赖项从缓存中“加载”，而一些依赖项“克隆”来自缓存？

Question

我正在尝试优化我的项目的composer install过程。我已经安装了Prestissimo，将我所有的dev依赖项移到‘require’中，并且在我的composer.json文件中将‘首选-install’设置为'dist‘。所有这些都把安装时间从4分钟缩短到2分钟。

我的依赖项包括我自己在Gitlab上的一些私有repos，当我观看composer安装过程时，我的repos说‘从缓存中克隆’，每个处理需要几秒钟，而所有其他依赖项都说‘从缓存加载’，并且几乎是立即处理。

这是composer.json

        { "type": "git", "url":  "git@gitlab.com:ti-cms/ti-tree.git" }
    ]
}

这是composer install输出。

因此，我的问题是，如何使我自己的包‘加载’从缓存，以加快我的安装过程？

Answer 1

我认为这只是git和准备好的包之间的区别，即克隆git与dist(zip/tar)文件。缓存后，只需解压缩zip文件，您就完成了。

对于git来说，克隆是一种需要更多时间的操作，很可能是通过网络来确保缓存的回购仍然是最新的，然后执行实际的缓存回购到工作目录克隆。

如果希望从缓存加载自己的包，请尝试以dist (zip/tar)格式分发它们。
