php - zlib_decode() : data error using composer in the doctrine2 tutorial

Question

更新: 我不久前按照评论中的建议将此问题发布到错误跟踪器，现在我运行了新版本的 composer 的全新安装(Composer 版本 7131607ad1d251c790ce566119d647e008972aa5 2014-05-27 14:26:24)，问题已解决。

原帖: 我正在尝试使用他们在 http://docs.doctrine-project.org/en/latest/tutorials/getting-started.html 上的教程来学习如何使用 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，我花了很多时间尝试处理 zlib_decode(): data error 问题，它绝对与您尝试安装的具体包无关。它必须与代理和/或不良的互联网连接有关。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。通过将此添加到您的 composer.json 来强制使用 HTTPS 进行包检索。

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

<强>2。如果问题仍然存在，请尝试运行 composer diag。就我而言，很少有消息:

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 并按照说明进行操作后 - 在下一次尝试中，一切正常。
