Python 3.4和2.7:无法为python 3.4安装numpy包

Question

我正在使用Ubuntu 12.04并希望与python 2.7并排使用python 3.4.

python 3.4的安装工作正常.但是,我无法安装python 3的numpy包(因此我无法安装scipy,pandas等).

运用

 sudo pip3 install numpy

吐出以下错误:

File "numpy/core/setup.py", line 289, in check_types

"Cannot compile 'Python.h'. Perhaps you need to "\

SystemError: Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.

顺便说一句,我已经安装了python-dev.

而且,安装numpy via

 sudo apt-get install python-numpy

不起作用,因为我已经为python 2.7安装了numpy,安装程序响应numpy已经是最新的.

我能做什么？谢谢!

Answer 1

您尚未安装Python 3 开发包.安装python3.4-dev:

apt-get install python3.4-dev

主程序包从不包含开发标题; Debian(以及扩展的Ubuntu)包策略是将它们放入一个单独的-dev包中.numpy但是要安装,您需要这些文件才能编译扩展.
