所以很明显，皮普没有正确地拿起它的手臂。正确的设置方法是什么？

我注意到，在上面的错误跟踪中，arm7l (由uname列出)没有作为一个选项列出，但无论如何尝试了如下：

ARCHFLAGS='-arch arm7l' pip install scipy

但是完全相同的输出。

我知道我可以apt-get install python-scipy，但是Id宁愿通过pip来完成它，这样我就可以使用最新的版本并完全控制我的环境(调试一个问题，在这个问题中，ubuntu打包的pip只挂在某些在x64上运行良好的函数上)。

编辑:尝试从每个这里的说明的源代码直接编译，但仍然是相同的问题，gfortran没有找到正确的拱。
