Python 2.7 ImportError:…/lib64/python2.7/site-packages/scipy/special//u ufuncs.so:undefined symbol:npy\u exp

我在CentOS 6.5上工作，默认情况下它有python 2.6。因此，我手动安装了Python2.7，并在“/home/thomas/Programs/python-2.7_项目”中使用virtualenv设置了一个沙箱

然后我编译了numpy和scipy，如下所示：

chmod -R 777 /home/thomas/Programs/python-2.7_project
source /home/thomas/Programs/python-2.7_project/bin/activate
export PYTHONPATH=/home/thomas/Programs/python-2.7_project/lib64/python2.7/site-packages:$PYTHONPATH
sudo yum remove numpy scipy
sudo yum -y install blas lapack atlas atlas-devel mercurial
sudo ln -s /usr/lib64/libblas.so.3 /usr/lib64/libblas.so
sudo ln -s /usr/lib64/liblapack.so.3 /usr/lib64/liblapack.so
sudo ln -s /usr/lib64/atlas/libatlas.so.3 /usr/lib64/atlas/libatlas.so
export BLAS=/usr/lib64/libblas.so
export LAPACK=/usr/lib64/liblapack.so
export ATLAS=/usr/lib64/atlas/libatlas.so

git clone git://github.com/numpy/numpy.git numpy
cd numpy
python setup.py build
python setup.py install --prefix=/home/thomas/Programs/python-2.7_project

# for scipy
pip install cython # necessary for scipy
git clone git://github.com/scipy/scipy.git scipy
cd scipy
python setup.py build
python setup.py install --prefix=/home/thomas/Programs/python-2.7_project

但是，当我从scipy.stats导入一些函数时，会出现以下错误：

Traceback (most recent call last):
  File "/usr/local/bin/RescoringTK.py", line 66, in <module>
    from scipy.stats import pearsonr, linregress, zscore

    from ._ufuncs import *
ImportError: /home/thomas/Programs/python-2.7_project/lib64/python2.7/site-packages/scipy/special/_ufuncs.so: undefined symbol: npy_exp

回溯（最近一次呼叫最后一次）：

有人知道错误的原因吗？

像Anaconda或CanopyIt这样的发行版更容易使用。它不提供python 2.7。Anaconda提供。我正在使用默认安装的Anaconda，Python2.7.6Wow！我要是早点发现就好了！非常感谢。
