作曲家中 require 和 install 与 create-project 之间的区别

Difference between require and install vs create-project in composer(作曲家中 require 和 install 与 create-project 之间的区别)

问题描述

我不明白 create-project 在作曲家中是如何工作的.让我们以 Laravel 为例.

I don't get how the create-project works in composer. Lets take Laravel as example.

我可以使用以下命令安装这个 PHP 框架:

I can install this PHP framework with the following command:

composer create-project laravel/laravel --prefer-dist

此命令为我安装框架，在我的目录的根目录中留下几个文件夹:

This command installs the framework for me leaving me with a few folder in the root of my dir:

• 应用
• 引导
• 公开
• 供应商

加上一些文件.

但是当我简单地使用以下composer命令时:

But when I simply use the following composer command:

composer require laravel/laravel --prefer-dist
composer install

那么这只会安装 vendor 文件夹.composer 不会下载其他文件和文件夹.

Then this only installs the vendor folder. No other files and folders are downloaded by composer.

怎么会?有什么不同?当我使用 create-project laravel/laravel 命令时，composer 如何知道要获取哪些其他文件以及为什么我在执行 require 时只获取 vendor 文件夹laravel/laravel?

How come? What is so different? How does composer know what other files to get when I use the create-project laravel/laravel command and why do I only get the vendor folder when I do require laravel/laravel?

推荐答案

require 会在 composer.json 文件中添加一个依赖并加载到 vendor 目录，正如您正确注意到的那样.

require will add a dependency to the composer.json file and load it into the vendor directory as you have correctly noticed.

create-project 将clone 依赖项，即将依赖项用作新项目的模板.看看 laravel/laravel 背后的仓库:https://github.com/laravel/laravel

create-project on the other hand will clone the dependency, i.e. use the dependency as a template for a new project. Take a look at the repository behind laravel/laravel: https://github.com/laravel/laravel
