Anaconda使用conda连接网络出现错误

在进行更新或者其他操作时报网络连接错误如下：

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(': Failed to establish a new connection: [Errno 10061] ',)))",),)

解决办法：

在系统用户user下找到.condarc文件，在里面添加：

channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
show_channel_urls: true

记得一定要删除 -defaults这一行
