Collecting package metadata (cur

这几天被conda折腾的不要不要, 之前是jupyter 用不了我把anaconda3和jupyter全部卸载了,现在jupyter可以用但是conda在命令行提示符prompt中运行出现如下错误

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json>

'https://repo.anaconda.com/pkgs/main/win-64'

百度一下说或许是C:/User/Mars>下的.condarc出了问题, 改成清华镜像没用, 试了一下

conda config --set channel_priority flexible
conda clean -i #清除索引缓存

也没有用, 我都把他删了,才知道冤枉人家了.

用笔记本打开看着.condarc,觉得https没http长得好看, 于是我删除http的后缀s, 只保留http,

channels:
  - defaults
show_channel_urls: true
channel_alias: http://mirrors.tuna.tsinghua.edu.cn/anaconda
default_channels:
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - http://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free

custom_channels:

  pytorch: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  simpleitk: http://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

结果成功了...

后来翻了翻网页才想起来https 是http+ssl的enhanced http, 只要整一下openssl也可以完成任务. 这个故事告诉我们一个道理: 战士, 编程永远是一个人的裸奔.
