Note

笔记

downside of using this method is that the main composer.json file would include some of the packages that have been required by existing or sub packages or multiple packages. but don't worry it would be installed only one time. but there might be problem with versions.

使用这种方法的缺点是主 composer.json 文件将包含现有或子包或多个包所需的一些包。但别担心它只会安装一次。但是版本可能有问题。

I recommend you use some version control like git to overcome such situations in future.

我建议你使用一些像 git 这样的版本控制来克服将来的这种情况。

can't guarantee about the following method i am going to present as its not a usual case. but might work.

不能保证我将介绍的以下方法不是通常的情况。但可能会起作用。

create a new composer.jsonfile like this in project root. you could use composer initcommand if you wish.

composer.json在项目根目录中创建一个这样的新文件。composer init如果你愿意，你可以使用命令。

• go to every package folder inside vendor folder and find the package's composer.jsonfile. from that file find the "name"of that package from that composer.json file.

• add that name of the package to the main composer.jsonfile's "require"part. if you want to add that package to development add it to "require-dev" part.

• composer installor composer update

• composer dump-autoload

• 转到 vendor 文件夹中的每个包文件夹并找到包的 composer.json文件。从那个文件中找到"name"那个 composer.json 文件中的那个包。

• 将该包的名称添加到主 composer.json文件的"require"部分。如果您想将该包添加到开发中，请将其添加到“require-dev”部分。

• composer install或者 composer update

• composer dump-autoload
