[SciPy-User] How to install scipy in virtualenv+python3+unbuntu12.04?

[Heng Zhou]

I want to install scipy in virtualenv and I'm using python3 and the OS is
ubuntu 12.04. Because virtualenv use pip to install third-party packages,
apt-get is not applicable. I read the install webpage but couldn't
understand what it is talking about. So, could you please give me a list of
workable command lines that I can follow to install scipy in
virtualenv+python3+unbuntu12.04? In addition, if there is any depandencies
needed before installation of scipy, please also included. Thank you very much.
