Question

更新：我刚刚在评论中建议将此问题发布到bug跟踪器，现在我运行了新版本作曲家的干净安装（作曲家版本7131607ad1d251c790ce566119d647e008972aa5 2014-05-27 14:26:24）并且问题已修复。

原始邮寄：我试图在http://docs.doctrine-project.org/en/latest/tutorials/getting-started.html

使用他们的教程学习如何使用doctrine2

但由于某种原因，我在尝试运行composer install时遇到此错误：

  [ErrorException]           
  zlib_decode(): data error

这是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。

编辑：composer install -vvv的输出：

Answer 1

在最后一天，我花费了大量时间来处理zlib_decode(): data error问题，这肯定与您尝试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做一些事情。禁用防病毒对我的情况没有帮助，因为我没有在我的Mac上使用防病毒软件。这些是最终有所帮助的事情。

<强> 1。通过将此添加到composer.json。

，强制HTTPS进行包检索

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

<强> 2。如果您仍遇到此问题，请尝试运行composer diag。在我的情况下，有一些消息是：

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

在执行composer self-update --update-keys并按照说明进行下一次尝试后，一切正常。

Answer 2

就我而言，它是Avast防病毒软件。禁用所有更新后没有问题。

Answer 3

如果您使用的是debian / ubuntu，只需在您的计算机上安装解压缩：

sudo apt-get install unzip

这对我有用！
