检查是否需要安装composer

Question

我有一个正在运行的项目，有一些依赖项。我正在做一些修改，并且需要一个新的包。因此，在我的开发平台上，我运行

composer require x/x

并且安装了该软件包。

现在我正在将其推向产品。因此，我已经安装了

vendor/

文件夹，其中安装了所有依赖项，但我还没有新包及其内容。我知道如果我运行

composer install

，我将安装新软件包而不是其他任何东西，但是有没有办法知道（命令）实际上有一个新软件包要安装？

出现这个问题是因为我不想每次在 CI/CD 中都运行

composer install

，而只在需要时才运行。有办法吗？

否则，我想我必须检查

composer.json

/

composer.lock

上的文件修改。

composer diagnose

的输出：

root@34ac8973c327:/app# composer diagnose

我已经尝试过

composer status

但它只显示您是否修改了

vendor/

中的文件（检查软件包的完整性），而不显示所有软件包是否正确安装了

composer.json

/

composer.lock

。

发布这个问题后我一直在寻找，我想我得到了答案。

我查看了运行日志

composer install

，看起来像这样（当没有什么可做的时候）：

然后我在 Github 上查看了 Composer 源代码，简单阅读后发现，我们运行

composer install

时所做的“差异”（为了只安装需要的包）是代码，但没有关联的直接命令。 通过快速阅读，它可以通过

installed.json

文件满足您的作曲家需求。

最后，我相信目前还没有任何composer命令能够满足我的具体需求。
