我的共享能力受到限制,因为这是我从Ubuntu 14.04移植到16.04的大量代码的一部分。
这应该是微不足道的,但是我却为此而苦苦挣扎。找不到numpy/arrayobject.h我在源文件中引用的#include <numpy/arrayobject.h>
我将尽力分享尽可能多的东西,看看是否有人可以指导我解决问题。

我在部分中断的Debian安装中遇到了相同的行为。
我通过重新建立符号链接来修复错误
sudo ln -s /usr/lib/python2.7/dist-packages/numpy/core/include/numpy /usr/include/numpy
你是如何安装numpy的?
如果您python-numpy正确安装,例如通过sudo apt-get install python-numpy,您将/usr/include/numpy链接到正确的路径:
$ ls -l /usr/include/numpy
lrwxrwxrwx 1 root root 55 Sep 17 2014 /usr/include/numpy -> ../lib/python2.7/dist-packages/numpy/core/include/numpy

看起来您可以手动构建 numpy,然后您可以相应地手动创建软链接。
