I'm running Laravel 5.5.
While trying to install jacquestvanzuydam/laravel-firebird via Composer,
but it fails. The Composer shows me:
[InvalidArgumentException]
Could not find a version of package jacquestvanzuydam/laravel-firebird matching your minimum-stability (stable). Require it with an explicit version constraint allowing its desired stability.
This package does not have any stable release. You need to specify branch in constrait directly:
composer require jacquestvanzuydam/laravel-firebird:dev-master
This will install version from master branch. List of available branches you can find or right column on https://packagist.org/packages/jacquestvanzuydam/laravel-firebird.
You may also report this issue (no stable release of this package) to package maintainer. Using branch instead of regular constraint may give unexpected compatibility breaks, you should really avoid it where possible.
Adding "minimum-stability": "dev" to composer.json before installation worked for me.

I did a lot of research on the web, but did not find a documentation of the composer error log. In the discussions I found, nobody had an explanation that was consistent with the error log. For example:
[Support] Need explanation for "Conclusion: don't install ..."
Why composer says "Conclusion: don't install" when (seemingly) no obstacles are present?
I know, what composer does and can resolve issues on my own, but I often have to consult packagist.org for this. Despite being quite (and unnecessarily) verbose, the composer log only gives me some hints. It does not really point out the concrete problems.
Does anyone know of a complete documentation or how to explain the reasoning behind the logs, maybe taking the above ones as an example?
Documentation of Composer can be found at getcomposer.org/doc, especially Troubleshooting section. Usually the dependency problems comes from misconfiguration of your composer.json and understanding Composer logs comes with experience or learning on trial and error. Documenting every possible errors out of hundreds can become quickly outdated. If you believe some specific error isn't clear enough, you can always raise a new suggestion at the Composer's GitHub page.
As suggested in linked GitHub issue, "Conclusion: don't install" message it could be related to requirements defined in minimum-stability. Another linked question could be related to Composer's bug as reported at GH-7215.
Errors
Here is a small guide explaining the common Composer's errors:
Can only install one of: org/package[x.y.z, X.Y.Z].
If you see this messages, that could be the main cause of the dependency issue. It basically means that based on the Composer's dependency calculation both of these versions are required, but only one major version can be installed (you cannot have both x.y.z and X.Y.Z, unless you split your configuration for different folders). To see why these packages are required, use the composer why/depends command and adjust the dependencies accordingly.
See: How to resolve a "Can only install one of:" conflict? & How to solve two packages requirements conflicts when running composer install?
Installation request for org/package2 (locked at vX.Y.Z)
This message means that there was an installation request for org/package, however, it is locked at X.Y.Z. If the requested version is not compatible with the locked version (like a different major version), you cannot install both. This message often comes along with already mentioned "Can only install one" one. So, whenever you see "locked at", that means Composer reads your installed package version from the composer.lock file. To troubleshoot, you can use composer why/depends command to find why the package was requested and adjust the compatibility, otherwise, you may try to remove composer.lock file and start from scratch (ideally from the empty folder).
See: Installation failed for laravel/lumen-installer: guzzlehttp/guzzle locked at 6.3.0
org/package1 vx.y.z conflicts with org/package2[vX.Y.Z].
It is a similar issue as above where two packages are conflicting and you need to solve the dependency manually. Reading the whole context of the message may give you some more clues. Checking the dependency tree may also help (composer show -t).
conflict with your requirements or minimum-stability
This message means as it reads, so you should check the required version and/or your minimum-stability settings.
This can be caused by a package being marked as non-stable and your requirements being "stable only. See: But these conflict with your requirements or minimum-stability
Or because of conflicts with other installed packages. See: How to identify what is preventing Composer from installing latest version of a package?.
For any other errors, check out the official Composer's Troubleshooting page.
Troubleshooting
Here are more suggestions how to troubleshoot the Composer dependency issues in general:
Add -v/-vv/-vvv parameter to your command for more verbose output.
Run composer diagnose to check for common errors to help debugging problems.
If you seeing "locked at x.y.z" messages, it relates to packages locked in your composer.lock.
Test your composer.json on the empty folder.
Keep your composer.json to minimum.
Run composer show -t to see your current dependency tree.
Run composer show -a org/package x.y.z to check the details about the package.
Feel free to ask a new question at Stack Overflow.
To fully debug Composer's dependency problem, you can:
Analyse or modify the source code (e.g. DependencyResolver/Problem.php).
Run Composer under XDebug, either by the breakpoint or generating a full or partial trace file.

How to identify what is preventing Composer from installing latest version of a package?
Error:
somevendor/somepackage[v1.0.0, ..., v1.9.1] require composer-plugin-api ~[X.X]
This means that that somevendor/somepacakge requires that a specific version range of Composer to be installed.
Run composer -v and compare it to the version constraint in the error message (shown as ~X.X in the example above, but that could be something like ^1.0, or ^2.2, etc).
If your version does not match the constraint, see if you can either:
upgrade or downgrade your composer version to match the composer constraint in the error message
upgrade somevendor/somepackage so that it can work with your Composer version.

Its a php package, u can't install with composer require

Do you already have a composer.json file in your directory? If not, this could be the error, because in this file you will configure which version of the package you want to install in to your project.
The second exception gives a hint to that missing version!
If you have a composer.json file please add its content to your question, so that we can take a look at it.
Here you can find further informations:

i faced the same problem.
And neither the creation of releases, nor any tags helped.
The solution for me turned out to be updating the composer from last version.
it's for composer, nothing else. If you already installed composer and composer version is 2 then convert it to version 1.easy way to solve this problem is ,delete the composer folder from your system and re install it. download from here: https://getcomposer.org/
I'm trying to make composer update only newly added packages to composer.json i.e when I manually add a package dependency to the composer.json file, it should update the composer.lock file only for the new package; the rest of the packages should be at the same version as before. I tried running composer update --lock but I don't think it does what I'm trying to achieve and it took a lot of time to finish. I checked the commands on composer's documentation but can't find one to achieve my wish. Any advice or workaround will be appreciated.
Note: I'm using Laravel Forge, so there is a 2 minutes deployment limit.
In order to install only new packages with composer you should run
composer install
Because composer update will install your new packages but will update and all the other already installed packages.
You can specify the name of the package as an argument to the update command. This will perform a partial update: composer update the-package/you-want-to-update
I think your question is related to your (guessed) current workflow: To add a new package you edit the composer.json file and then run composer update - wishing to only add/update that new file.
If that is true, here is the solution:
composer require new/package will add the newest possible version (taking into account the currently installed packages) of the new package. Benefits: Only one command line, and no fiddling with JSON content.
If you already know which version you want, you could also run composer require new/package:^2.1.25#beta (or whatever version and stability level you want - this example is exaggerating a bit). If this version is incompatible with existing packages, nothing will get installed, everything will get rolled back, and you get an error message.
I pushed my package medyes/ebay-api on github.
When I tried to download it on another project with composer I have an error:
Command composer:
composer require medyes/ebay-api:dev-master
The error:
[InvalidArgumentException]
Could not find package medyes/ebay-api at any version for your
minimum-stability (dev). Check the package spelling or your minimum
-stability
this is the composer.json of medyes/ebay-api package
composer.json
Avoid using branches - especially when the project you are about to include offers tagged versions.
composer require medyes/ebay-api:~0.1
This will update this package until version 1.0 comes out (which would not be installed, because that major release number change it is considered incompatible according to semantic versioning) every time a newer, installable version exists and you run composer update.
Trying to install the KnpGaufretteBundle in a Symfony 2.3 project, I'm having no luck. The problem is:
minimum-stability:stable (in composer.json);
the bundle I require is dev-master version still.
Reading this in the Symfony docs was frustrating:
If you know of a cool bundle or PHP library that still requires a dev
minimum stability, talk to the lead developer and convince him to tag
a stable release.
I'm not changing the minimum stability of the whole project to dev, as it would certainly make a huge mess - I mean, can't I use stable packages and dev packages side by side?
Am I missing something about composer maybe?
Edit (14 August 2013)
According to Sven's answer below, I've edited my composer.json (you can find it here) and it started to work. Anyway, this is a partial solution, because inline aliases do not work for dependencies - so in my case I'd have to specify all dependencies of "less-than-stable" packages first, and alias them one by one.
just use
"knplabs/knp-gaufrette-bundle": "dev-master#dev"
if you need the latest dev version
you can also change minimum-stability to dev and add "prefer-stable": true like this:
"minimum-stability": "dev",
"prefer-stable": true,
then composer will always try to find a stable version and if nothing found install dev, so your symfony packages will be still stable.
But in your case composer will install v0.1.4 (latest stable of knplabs/knp-gaufrette-bundle), so you need dev-master#dev anyway. prefer-stable is just a hint for you.
Have a look at aliases: http://getcomposer.org/doc/articles/aliases.md
They are supposed to allow you to address a branch (which by definition is always in development, because you can only access the latest commit) in a way that that branch should be the logical extension of a version tag.
For a yet untagged project, a proper assumed tag version would be like "0.0.0".
You should try the inline alias for the bundle.
