致命错误:numpy/arrayobject.h:没有这样的文件或目录

Question

我可以分享的内容有限，因为这是我从 Ubuntu 14.04 移植到 16.04 的大量代码堆栈的一部分。

这应该是微不足道的，但不知何故，我正在为此苦苦挣扎。它找不到我在源文件中引用numpy/arrayobject.h#include <numpy/arrayobject.h>

我会尽可能多地分享，看看是否有人可以指导我完成解决方案。

错误

make命令导致

+++ Compile mycore/boost_numpy.cc to build.x86_64-linux2-gcc

磁盘上numpy/arrayobject.h声明文件

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

请让我知道如何改进问题。欢迎提供方向或指示

更新

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

解决方法为

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

Answer 1

我在部分损坏的 Debian 安装上遇到了相同的行为。

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

你是如何安装 numpy 的？

如果您正确安装python-numpy，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您的 numpy，然后您可以相应地手动创建软链接。
