使用 chef 安装 python 时出现“CRC check failed”

Question

我正在尝试使用 chef-solo 和 vagrant 将石墨安装到 64 位 Lucid VM 上。石墨的依赖项之一是 python，当我尝试配置 VM 时，出现以下错误。我正在使用来自 Opscode (https://github.com/opscode-cookbooks/python) 的标准 python 食谱

我不熟悉 chef 或 python，所以这个错误让我有点难过。任何帮助表示赞赏。

错误IOError: CRC check failed 0x94c615b3 != 0x2e611106L 表示gzip 模块无法解压下载的.tgz 文件。这可能是由网络问题引起的。

要隔离此问题，请尝试运行命令手动设置分发，即运行vagrant ssh，然后：

/usr/bin/python distribute_setup.py --download-base=https://pypi.python.org/packages/source/d/distribute/

这应该可以帮助您缩小进程在distribute_setup.py 文件中出错的位置。如果distribute_setup.py 失败，那么您可以检查它下载的distribute-X.Y.Z.tar.gz 文件以查看它是否与https://pypi.python.org/packages/source/d/distribute/ 中的文件匹配（获取两个文件的md5sum 以验证它们是否相同）。如果它们相同，我会尝试提取刚刚手动下载的 .tgz 以查看它是否有效；我想可以想象网站上的其中一个文件已损坏，尽管这似乎不太可能。

如果此时解决方案不是很明显，请使用这些额外的诊断更新您的问题，我们将看看可以做哪些进一步的挖掘。
