Description: ------------ Currently, the pear/html_common package registered on Packagist.org (composer repository) has two versions available: dev-trunk and dev-topics/composer-for-pear. However, pear/html_table requires pear/html_common version ^1.2.5. Composer fails to find that, because there is no version tagged with the version number available on Packagist. I'm reporting this here, because I do not see any contact details for the maintainer of this package on Packagist. Test script: --------------- Example 1 composer.json file: { "require": { "pear/html_common": "^1.2.5" } } Example 2 composer.json file. Even explicitly allowing dev versions does not help: { "minimum-stability": "dev", "require": { "pear/html_common": "^1.2.5@dev" } } Actual result: -------------- Example 1 fails: $ composer install Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested package pear/html_common ^1.2.5 exists as pear/html_common[dev-topics/composer-for-pear, dev-trunk] but these are rejected by your constraint. Example 2 fails: $ composer install Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested package pear/html_common ^1.2.5@dev exists as pear/html_common[dev-topics/composer-for-pear, dev-trunk] but these are rejected by your constraint.
