一台计算机上同时安装了python2.7和python3.7。
现在为python2.7安装numpy包。
C:\Python27>python2 -m pip install numpy -i http://mirrors.aliyun.com/pypi/simple/

开源科学计算包 NumPy 系统是 Python 的一种开源的数值计算扩展,该工具可用来存储和处理大型矩阵。NumPy 1.16.0 支持 Python 2.7 和 3.5-3.7,不再支持 3.4。
NumPy 以后发布的版本将只支持 Python 3。
======================
如果在同一台机器上有两个版本的Python,则应明确指定您的pip版本:
#Find all versions available: python2.7 -m pip install scikit-image== #Then install your prefer/latest version from the list above. Example: python2.7 -m pip install scikit-image==0.14.2
