Zlib_decode (): data error using composer in doctrine2 tutorial

Question

UPDATE: I posted this problem to the error tracker some time ago, as suggested in the comments, and now I have cleaned the new version of the composer (Composer version 7131607ad1d251c790ce566119d647e008972aa5 2014-05-27 14:26:24) and the problem has been fixed.

ORIGINAL MAIL: I'm trying to learn how to use doctrine2 using their tutorial at http://docs.doctrine-project.org/en/latest/tutorials/getting-started.html

but for some reason I get this error when trying to run composer install :

  [ErrorException] zlib_decode(): data error 

Here is the content of composer.json:

 { "require": { "doctrine/orm": "2.4.*", "symfony/yaml": "2.*" }, "autoload": { "psr-0": {"": "src/"} } } 

EDIT: PHP Version 5.5.9.

EDIT: output of composer install -vvv :

Answer 1

Over the last day, I spent a lot of time solving the zlib_decode(): data error problem, and this is definitely not related to which package you are trying to install. It must do something with a proxy server and / or with a poor internet connection. Disabling antivirus did not help my case, since I do not use antivirus on my Mac. This is what helped in the end.

1. Force HTTPS to search for packages by adding this to your composer.json .

 { "repositories": [ { "type": "composer", "url": "https://packagist.org" }, {"packagist": false} ], "require": { /* your packages as usual */ } } 

2. If the problem still occurs, try running composer diag . In my case, several posts were:

 Checking pubkeys: FAIL Missing pubkey for tags verification Missing pubkey for dev verification Run composer self-update --update-keys to set them up 

After running composer self-update --update-keys and following the instructions, the next time everything worked fine.

Answer 2

In my case, it was an Avast antivirus. After disabling all updates without problems.

Answer 3

Just install unzip on your computer if you are using debian / ubuntu:

 sudo apt-get install unzip 

It works for me!
