Loading required packages from pear repository fails

[ComaVN]

I used to be able to load pear packages from the default pear repository (pear.php.net), but this no longer works: I get The requested package pear-pear/pear could not be found in any version

See https://github.com/ComaVN/ComposerPearTest for my composer.json

I have also tried:

• lowering minimum-stability to dev
• requiring other pear packages like pear-pear/mail and pear-pear/mail_mime
• explicitly requiring the latest version 1.9.5
• explicitly requiring the dev or dev-master version

None of this worked.

I have also tried skipping the pear repository, and using packagist instead: https://packagist.org/packages/pear/pear

However, this gave me a warning: Warning: Ambiguous class resolution, "PEAR_ErrorStack" was found in both "/Users/foo/git/ComposerPearTest/vendor/pear/pear/PEAR/ErrorStack.php" and "/Users/foo/git/ComposerPearTest/vendor/pear/pear/PEAR/ErrorStack5.php", the first will be used..

What am I doing wrong here?

  Problem 1
    - The requested package pear-pear/pear could not be found in any version, there may be a typo in the package name.

Potential causes:

The warning was introduced recently and is nothing more than just that, a warning. See #4260 for more details. I don't know why pear-pear/pear will not install though.

try using pear-pear.php.net/pear instead (i.e. the channel name rather than the channel alias). I think channel aliases are broken

[ComaVN]

using pear-pear.php.net/pear works, thanks
