Как установить numpy на Python 2.7 в virtualenv?

Я пытаюсь установить numpyна (на Cygwin). Python 2.7Однако , когда я пытаюсь , я получаю :virtualenv

Есть ли у вас предложения по установке numpy на Python 2.7 в virtualenv?

Примечание:
версия Python3 в Cygwin — 3.6, и, похоже, pypi numpy еще не готов к 3.6.

Редактировать 1:

В ответ намацерикомментарий, я удалил numpyиз pip3 и pip2 и установил numpyдля Python 3 и Python 2 из setup.exe Cygwin.
Ниже приведены ошибки, которые я получаю для numpy, когда пытаюсь импортировать его впоследствии:

Установите пакет python2-numpyс помощью установки cygwin. Для его установки pip не нужен.

python2 -c "import numpy"работает для меня.
Поскольку проблема кажется на lapack_liteчеке, что у вас /usr/lib/lapack/на пути.

$ cygcheck -l liblapack0
/etc/profile.d/lapack0.csh
/etc/profile.d/lapack0.sh
/usr/lib/lapack/cygblas-0.dll
/usr/lib/lapack/cyglapack-0.dll


 $ cygcheck /usr/lib/python2.7/site-packages/numpy/linalg/lapack_lite.dll | grep -v Windows
E:\cygwin64\lib\python2.7\site-packages\numpy\linalg\lapack_lite.dll
  E:\cygwin64\bin\cygwin1.dll
  E:\cygwin64\lib\lapack\cyglapack-0.dll
    E:\cygwin64\bin\cyggcc_s-seh-1.dll
    E:\cygwin64\bin\cyggfortran-3.dll
      E:\cygwin64\bin\cygquadmath-0.dll
    E:\cygwin64\bin\cygblas-0.dll
  E:\cygwin64\bin\libpython2.7.dll

В противном случае библиотека lapack не будет работать.
