Could not find a version that satisfies the requirement numpy>=1.7.0 (from pan das==0.17.0) (from versions: ) No matching distribution found for numpy>=1.7.0 (from pandas==0.17.0)

今天晚上一直在安装pandas,天杀的，真的是太难了。后来发现提示：

Could not find a version that satisfies the requirement numpy>=1.7. (from pan
das==0.17.) (from versions: )
No matching distribution found for numpy>=1.7. (from pandas==0.17.)

更新numpy的版本步骤如下：

1.查看当前numpy安装包版本：pip  show   numpy

2.百度需要的numpy版本：  https://pypi.org/project/numpy/1.11.2/#files

3.下载需要的版本：numpy-1.11.2-cp27-none-win32.whl

4.安装需要的版本：pip install  C:\Python27\Scripts\numpy-1.11.2-cp27-none-win32.whl

5.出现成功安装提示
