The following links are not helpful because I do not have root right and cannot use sudo.
以下链接没有帮助，因为我没有 root 权限并且无法使用 sudo。

python-dev is not a python module. Actually it's "Header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications." You can install it through Synaptic Package Manager,Software Center or yum.
python-dev 不是 python 模块。实际上它是“用于构建 Python 模块、扩展 Python 解释器或在应用程序中嵌入 Python 的头文件、静态库和开发工具”。您可以通过 Synaptic Package Manager、软件中心或 yum 安装它。

If you are in Ubuntu(e.g. Ubuntu 12.04), it is very easy,
如果您使用的是 Ubuntu（例如 Ubuntu 12.04），这很容易，
sudo apt-get install python-numpy
or you can compile from source through pip(I think on RedHat almost the same):
或者你可以通过 pip 从源代码编译（我认为在 RedHat 上几乎相同）：
sudo apt-get install python-dev
sudo apt-get install python-pip
pip install numpy

On CentOS, the python development libraries are under the name python-devel, not python-dev.
在 CentOS 上，python 开发库的名称是 python-devel，而不是 python-dev。
Use sudo yum install python-develto install them on your CentOS system.
使用 sudoyum install python-devel在你的 CentOS 系统上安装它们。
