python Anaconda使用conda连接网络出现了error，anacondaconda,我使用的是windows

我使用的是windows10 64bit下的Anaconda2，在安装和更新包的时候出现以下报错信息。
这是使用默认源安装包的报错信息：
C:Usersning0>conda install numpy
Fetching package metadata ...

CondaHTTPError: HTTP None None for url https://repo.continuum.io/pkg...
Elapsed: None

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
ProxyError(MaxRetryError("HTTPSConnectionPool(host='repo.continuum.io', port=443): Max retries exceeded with url: /pkgs/free/win-64/repodata.json.bz2 (Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x00000000048F3048>: Failed to establish a new connection: [Errno 10061] ',)))",),)

下面是使用清华大学的镜像安装的报错信息：
C:Usersning0>conda install numpy
Fetching package metadata ...

求问这个问题怎么解决啊？我各种网站都找遍了。
