Composer - The requested package exists as but these are rejected by your constraint

问题:

When I run my install from composer, I have this error :

λ composer install You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.

Error :

Problem 1 - The requested package antoineb1/smoney_bundle 1.0 exists as antoineb1/smoney_bundle[dev-master] but these are rejected by your constraint.

My composer.json

{     "name": "project",     "license": "proprietary",     "type": "project",     "minimum-stability": "dev",     "prefer-stable" : true,     "autoload": {         "psr-4": {             "": "src/"         }     },     "config": {         "preferred-install": "dist"     },     "repositories": [         {             "url": "bitbucket url",             "type": "vcs"         }     ],     "require": {         "php": ">=5.5.9",         "antoineb1/smoney_bundle": "1.0"     } } 

回答1:

The version constraint "1.0" is interpreted internally as "1.0.0.0-stable" version.

But the only version available is:

antoineb1/smoney_bundle[dev-master].

So you could change the specified version to either one of the following depending on what version is suitable for you:

• 1.0.* (which is seen by composer as >=1.0.0.0-dev <1.1.0.0-dev -- probably won't work because there obviously aren't any versions in that package)
• dev-master
• dev-master#<hash>
• @dev
• etc.

See the composer schema for reference.

The comment by @Guillaume below this answer deserves a larger presentation.

It seems that composer wants a git release that has a v in it.

So it should be v1.1.0 and not 1.1.0.

I spent about 90 minutes looking at

mikeill/my_repo 3.3.10 requires composer/installers 1.0.*@dev -> satisfiable by composer/installers[1.0.x-dev, v1.0.0, ...] but these conflict with your requirements or minimum-stability.

And a lot of github issues as well as an SO post or two before finally discovering this thread.
