我正在 Cygwin 中尝试import numpy。我收到以下错误消息。
我已经通过 Cygwin 安装程序安装了 ，numpy 1.11.2-1也就是该python2-numpy: Python scientific computing module软件包。我还有Python 2.7.14-1，也就是该python2: Python 2 language interpreter软件包也是通过 Cygwin 安装的。我的机器上没有本地安装 Python。
$ python
Python 2.7.14 (default, Oct 31 2017, 21:12:13)
[GCC 6.4.0] on cygwin
Type "help", "copyright", "credits" or "license" for more information.

似乎有很多关于这个问题的帖子，但都没有适合我的解决方案。我尝试重新启动我的电脑https://stackoverflow.com/questions/42320132/not-able-to-import-numpy-in-cygwin，但这没有作用。
我还编辑了我的$PATH变量：
$ echo $PATH
/usr/lib/python2.7/site-packages/numpy/:/usr/lib/python2.7/site-packages/:/usr/bin
