zlib_decode():doctrine2教程中使用composer时发生数据错误

Question

更新：不久前，我按照评论中的建议将这个问题发布到了错误跟踪器上，现在我运行了新版本composer的干净安装(composer版本7131607ad1d251c790ce566119d647e008972aa5 2014-05-27 14:26:24(，问题已经修复。

原帖：我正在尝试使用他们的教程学习如何使用doctrine2http://docs.doctrine-project.org/en/latest/tutorials/getting-started.html

但由于某种原因，我在尝试运行composer install:时遇到了这个错误

  [ErrorException]           
  zlib_decode(): data error

以下是composer.json:的内容

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

编辑：PHP版本5.5.9。

EDIT：composer install -vvv:的输出

Answer 1

在过去的一天里，我花了很多时间试图处理zlib_decode(): data error问题，这肯定与您要安装的确切软件包无关。它必须与代理和/或糟糕的互联网连接有关。禁用防病毒软件对我的情况没有帮助，因为我没有在Mac上使用防病毒软件。这些都是最终有所帮助的东西。

1.通过将HTTPS添加到您的composer.json中，强制HTTPS进行包检索

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

2.如果您仍然遇到问题，请尝试运行composer diag。在我的案例中，很少有消息是：

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

在完成composer self-update --update-keys并按照说明进行下一次尝试后，一切都很好。

Answer 2

在我的案例中，它是Avast防病毒软件。禁用所有更新后没有问题。

Answer 3

如果您使用debian/ubuntu:，只需在您的机器上安装解压缩即可

sudo apt-get install unzip

这对我有用！
