How to remove unused dependencies from composer?
提问by Lorenz Meyer
I installed a package with composer, and it installed many other packages as dependencies.
我用 composer 安装了一个包，它安装了许多其他包作为依赖项。
Now I uninstalled the main package with composer remove packageauthor/packagename, but all the old dependencies were not removed. I expected composer to clean up and only keep packages that are required according to composer.jsonand their dependencies.
现在我用 卸载了主包composer remove packageauthor/packagename，但没有删除所有旧的依赖项。我希望作曲家清理并仅保留根据composer.json及其依赖项所需的包。

The right way to do this is:
正确的做法是：
composer remove jenssegers/mongodb --update-with-dependencies
I must admit the flag here is not quite obvious as to what it will do.
我必须承认这里的标志对于它将做什么不是很明显。
Update
更新
composer remove jenssegers/mongodb
As of v1.0.0-beta2--update-with-dependenciesis the default and is no longer required.
从v1.0.0-beta2 开始--update-with-dependencies是默认值，不再需要。

In fact, it is very easy.
事实上，这很容易。
composer update
will do all this for you, but it will also update the other packages.
将为您完成所有这些，但它也会更新其他软件包。
To remove a package without updating the others, specifiy that package in the command, for instance:
要删除一个包而不更新其他包，请在命令中指定该包，例如：
composer update monolog/monolog
will remove the monolog/monologpackage.
将删除monolog/monolog包。
Nevertheless, there may remain some empty folders or files that cannot be removed automatically, and that have to be removed manually.
尽管如此，仍可能存在一些无法自动删除的空文件夹或文件，必须手动删除。

following commands will do the same perfectly
以下命令将完美地做同样的事情
rm -rf vendor
composer install
回答by Valentas
Just run composer install- it will make your vendordirectory reflect dependencies in composer.lockfile.
只需运行composer install- 它将使您的vendor目录反映composer.lock文件中的依赖项。
In other words - it will delete any vendor which is missing in composer.lock.
换句话说 - 它会删除任何在composer.lock.
Please update the composer itself before running this.
请在运行之前更新作曲家本身。
