centos中virtualenv安裝scipy

由於項目須要scipy，在virtualenv中安裝scipy，參考官方安裝說明http://www.scipy.org/scipylib/building/linux.html，須要numpy,pip install numpy很簡單安裝好了，可是pip install scipy時一直報錯：

numpy.distutils.system_info.BlasNotFoundError: Blas (http://www.netlib.org/blas/) libraries not found. Directories to search for the libraries can be specified in the numpy/distutils/site.cfg file (section [blas]) or by setting the BLAS environment variable.

大stackoverflow.com救了我。

yum install lapack lapack-devel blas blas-devel pip install numpy pip install scipy

不得不說這個包好大，compile了好長時間。
