作曲家/Laravel:如何添加/更新特定的程序包 [英] Composer/Laravel: How to add/update a specific package

问题描述

如何使用composer添加/更新特定的软件包?我也正在使用最新的Laravel，但不确定是否重要，但可以帮助确定答案的任何内容.

How do you add/update a specific package using composer? I'm using the latest Laravel as well not sure if it matters but anything that can help to determine the answer.

我也从我发现的旧Stackoverflow帖子中尝试了以下内容，但对我而言不起作用.它将包附加到composer.json，然后继续更新所有内容.这是链接:如何使用作曲家?

I have also tried the following from an old Stackoverflow post I had found, but it didn't work for me. It appended the package to composer.json and then proceeded to update everything anyways. Here is the link: How to update a single library with Composer?

这是我尝试添加到项目中的软件包: https://github.com/barryvdh /laravel-dompdf

And here is the package I tried to add to my project: https://github.com/barryvdh/laravel-dompdf

非常感谢您的时间和帮助！

Thank you very much for your time and help!

需求和更新不起作用，它们也会更新所有内容.我是否可能错误地运行了命令?在作曲家:S

Require and update are not working they update everything as well. Is it possible that I'm running the command incorrectly? I'm still green behind the ears when it comes to composer :S
