我正试着在我公司的电脑里安装Pandas。我试着做了

pip install pandas

但是操作重试然后超时。
然后我下载了这个软件包：
Pandas-0.22.0-cp 27-cp 27 m-温_amd64.whl
并安装：

pip install pandas-0.22.0-cp27-cp27m-win_amd64

但我得到了以下错误：

Retrying (Retry(total=4, connect=None, read=None, redirect=None,
status=None)) after connection broken by
'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection
object at 0x0000000003F16320>, 'Connection to pypi.python.org timed

      Could not find a version that satisfies the requirement pytz>=2011k (from pandas==0.22.0) (from versions: )
    No matching distribution found for pytz>=2011k (from pandas==0.22.0)

我对package做了同样的处理：pandas-0.22.0-cp27-cp27m-win_amd64.whl
我还尝试使用代理：

pip --proxy=IND\namit.kewat:xl123456@192.168.180.150:8880 install numpy

但是我无法得到Pandas。
当我试图访问网站时：https://pypi.org/project/pandas/#files我可以在资源管理器上毫无问题地访问它
