【问题描述】：

使用easy_install numpy 安装numpy 时出现以下异常，有人可以帮忙吗？无论我使用pip 还是easy_install，我都遇到了同样的问题。很难理解出了什么问题。

【问题讨论】：

我认为gcc: internal compiler error: Killed (program cc1) 是关键。看来您需要提交错误报告。

我只是做了一个apt-get upgrade gcc，现在一切正常。谢谢。

@hilau 你能把它添加到答案中吗？

【参考方案1】：

也许 GCC 没有更新。我刚刚做了一个apt-get upgrade gcc和numpy编译成功。

【讨论】：

你最终使用了哪个版本的 gcc？我有 gcc 4.6.3，但仍然看到错误。

【参考方案2】：

您只需要使用此命令而不是 easy_install。为我工作

sudo apt-get install python-numpy python-scipy

【讨论】：

谢谢。我通常在virtualenv 中安装包，所以在开发多个项目时不会污染全局命名空间。首选easy_install。

apt-get install 不会在 virtualenv 中安装包。我不想污染全球环境。

-1 建议的答案与 virtualenv 相关的问题不符，virtualenv 的目的是管理与全局（系统）包分离的包的不同 virsions。
