轻松安装交叉编译的netifaces 0.8 python模块失败，因为它；找不到合适的分布”；

我正在Ubuntu 12.04.4 32位主机上使用Digi Embedded Linux工具链交叉编译ARM的“netifaces”Python模块，但在让目标设备正确安装时遇到了麻烦。最后，我想在我的rootfs中包含netifaces的工件，但这是后面的事情

以下是我的交叉编译步骤：

$ wget https://pypi.python.org/packages/source/n/netifaces/netifaces-0.8.tar.gz

（上面的代码段更改了路径以保护无辜者。）

我知道编译是针对ARM（而不是主机）的，因为以下内容似乎是正确的：

$ file build/lib.linux-i686-2.7/netifaces.so

build/lib.linux-i686-2.7/netifaces.so: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, not stripped

这给了我一个dist/netifaces-0.8-py2.7-linux-arm.egg工件。我将这个工件复制到我的目标设备并运行easy_install（没有可用的pip）。我不希望目标设备访问internet从pypi获取内容，因为这个设备需要有一个受控的配置，并且设备上没有编译器可以编译pypi包。它是这样的错误：

我还尝试了上面的命令，将“netifaces”作为包参数，但没有成功

当我删除'-H None'参数（允许它访问pypi）时，我确实得到了不同的结果，但它显然是错误的，因为没有可用的编译器。无论如何，我不想使用这种方法，但为了完整起见，我在这里包含了它
