为什么 Composer 中的依赖项更新如此缓慢? [英] Why updating of dependencies in composer is so slow?

问题描述

我正在使用 composer (http://getcomposer.org/) 来管理 Symfony2 中已安装的包(symfony v 2.1.3).作曲家的版本是 de3188c.

I am using composer (http://getcomposer.org/) to manage installed bundles in the Symfony2 (symfony v 2.1.3). Version of the composer is de3188c.

我遇到的问题是，当我将新包添加到 composer.json 并执行它时，显示有关更新依赖项和下一次下载它们的消息的时间非常低.

I have problem that when I add new bundle into the composer.json and execute it the time to show messages about Updating dependencies and next downloading them all is very low.

我在 composer.json 中有这些数据(见下文)，执行时间大约是 20 分钟！！！互联网连接速度足够快，我可以非常快地下载大文件...

I have this data in the composer.json (see below) and the executing time is approximately 20 MINUTES!!! The internet connection is fast enough I can download big files very fast...

有什么技巧可以让它更快?

Is there any trick to make it faster?

推荐答案

尝试在composer.json中为每个依赖指定一个版本，调用composer时使用选项--prefer-dist.它将从存储库(如果可用)而不是单个文件下载 ZIP 文件.

Try to specify a version for each dependency in composer.json and use the option --prefer-dist when calling composer. It will download ZIP files from the repositories (if available) instead of the single files.

php composer.phar install --prefer-dist
