There are times you may want to update a single Composer package without updating everything in your project all at once. I’ve put together a few tips to keep in mind when using this workflow.
Recently, I’ve been testing the newly-released ScoutAPM support for Laravel. (More on that in a future blog post.) I ran into an issue with Blade directives from third-party packages. Two days later, they published a new version which fixed the bug, hooray!
In order to test this, I needed to upgrade the
scoutapm/scout-apm-laravel package from version 1.2.1 to version 1.2.3. Since this is a patch release, it should be pretty straightforward to update this one package:
composer update scoutapm/scout-apm-laravel, right? Let’s try it using the handy
(Note: my project runs in Docker, so I’m calling
bin/dev/composer which is just a thin wrapper to run composer from inside the container)
That’s no good. It’s saying there’s nothing to update, but I know there’s an update available because it shows one when I run
Yep, there’s definitely an update available, but it’s that second line which gives us a hint why Composer is choosing to not update our single package. One of our package’s dependencies has bumped to a new major version, and our current pacakge has the dependency for
scoutapp/scout-apm-php pegged to
^3.1. Composer is dutifully following our instructions and refusing a major version update for this dependency.
One option would be to run
composer update scoutapp/scout-apm-laravel --with-dependencies which is our way of telling Composer it’s okay for those dependencies to be updated as well:
It’s interesting to note that Composer is still unwilling to update a dependency if it’s also specified in our composer.json file. That’s what it means when it says it’s ignoring a “root requirement.” The good news is our dry run now shows it is updating our single package. This is great! But, I’m still a little cautious and I’d rather not update those other packages if I don’t have to. Let’s see if we can be more specific:
And this is exactly what I want. We have a winner!
One final side note: the order of these packages is important. If I reversed them and listed
scout-apm-laravel first, it still wouldn’t update anything.
