python - 为什么我的 numpy 安装一直被杀死？

Question

这是我在 Coding Ground 上尝试做的事情

sh-4.3$ pip install --target=. virtualenv
You are using pip version 7.1.0, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

为什么我尝试安装 numpy 总是被杀死？我该如何解决这个问题？

Answer 1

对此的快速修复是添加交换内存。这是一个 Ubuntu 示例:

sudo mkdir /media/fasthdd
dd if=/dev/zero of=/media/fasthdd/swapfile.img bs=1024 count=1M
sudo mkswap /media/fasthdd/swapfile.img
sudo swapon /media/fasthdd/swapfile.img

如果不需要，请不要忘记将其关闭。
