致命错误：numpy/arrayobject.h:没有这样的文件或目录

Question

由于这是我从Ubuntu 14.04移植到16.04的一大堆代码的一部分，所以我只能分享一些东西。

这应该是微不足道的，但不知怎的，我正在挣扎。它找不到我用#include <numpy/arrayobject.h>在源文件中引用的numpy/arrayobject.h

我会尽量和大家分享，看看有没有人能引导我通过一个决议。

错误

make命令导致

我的源文件

磁盘上的声明文件numpy/arrayobject.h

root@deploy:/home#  find / -name arrayobject.h
/usr/local/lib/python2.7/dist-packages/numpy/core/include/numpy/arrayobject.h

请告诉我如何改进这个问题。最受欢迎的是方向或指针

更新

$ ls -l /usr/include/numpy
ls: cannot access '/usr/include/numpy': No such file or directory

解决方式

sudo ln -s  /usr/local/lib/python2.7/dist-packages/numpy/core/include/numpy /usr/include/numpy

Answer 1

在一个部分损坏的Debian安装中，我也经历过同样的行为。

我通过重新建立符号链接修复了错误

sudo ln -s /usr/lib/python2.7/dist-packages/numpy/core/include/numpy /usr/include/numpy

Answer 2

你是怎么安装numpy的？

如果正确安装python-numpy，例如通过sudo apt-get install python-numpy，则/usr/include/numpy将链接到正确的路径：

$ 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一个软链接。
