问题描述

但是，我丢失了 composer.json 。

是否有一种方法可以从供应商<>的内容重新创建 composer.json / code>目录？

Is there a way to recreate composer.json from the content of the vendor directory?

推荐答案

通过检查可以轻松实现已安装的识别

Identifying the installed dependencies can be easily achieved by inspecting

vendor
└── composer
    └── installed.json

但是，您将面临以下问题：

However, you will be faced with the following problems:

installed.json 列出了所有已安装的依赖项，即两者

installed.json lists all installed dependencies, that is, both

• 直接和


• 间接

依赖项。

直接依赖项是在
<$ c $中明确列出的依赖项c> require 和 require-dev 部分。

Direct dependencies are dependencies that are explicitly listed in the require and require-dev sections.

间接依赖关系是您的依赖关系直接依赖项。

Indirect dependencies are dependencies of your direct dependencies.

也就是说，尽管您可以通过编程方式p屁股 installed.json 和
收集其中列出的依赖项，您需要自己为
决定是直接依赖项还是间接依赖项，还是其他
个字，无论您是否要明确地，都需要
composer.json 中的这些依赖项。

That is, while you could programmatically parse installed.json and collect the dependencies listed therein, you will need to decide for yourself whether these are direct or indirect dependencies, or in other words, whether you want to explicitly require these dependencies in composer.json.

installed.json 列出全部已安装依赖项，即取决于
是否运行

installed.json lists all installed dependencies, that is, depending on whether you ran

$ composer install

或

$composer install --no-dev

， installed.json 将包含
直接和间接依赖项，列在

before you lost your composer.json, installed.json will contain direct and indirect dependencies listed in

$中b $ b
• require 和 require-dev 或


• require

• require and require-dev or
• require

个部分。

也就是说，您需要自己确定这些是否是
依赖项，这些依赖项应在

That is, you will need to decide for yourself whether these are dependencies which should be listed in the

• 要求 或


• require-dev

• require or
• require-dev

部分。

部分的目的和区别的更多信息。

installed.json 列表 all 安装了 exact
版本的依赖项。

installed.json lists all installed dependencies with the exact versions installed.

但是，您丢失的composer.json 并没有列出具有确切版本的
依赖项，而是使用了多种可能性
之一来指定版本约束。

However, the composer.json you lost in all likelihood did not list dependencies with exact versions, but using one of the many possibilities for specifying version constraints.

也就是说，您将需要自己决定是否要使用确切的版本，或者放宽约束，例如，使用

That is, you will need to decide for yourself whether you want to use exact versions, or relax the constraints, for example, by using

• 〜运算符


• ^ 运营商


• 等。

• the ~ operator
• the ^ operator
• etc.
