Can you tell me what should I do next? I surfed other links and setting ssl_verify: False didn't work for me

回答1:

I am experiencing the same issue, and am quite confident it is due to SSL/Firewall issues internally in the workplace.

Do you have proxy servers that you need to specify in your .condarc file? (.e.g)

proxy_servers:
    http : http://101.101.101.255:8080
    https : https://101.101.101.255:8080

I know it says WinXP but this still applies - https://conda.io/docs/user-guide/configuration/use-winxp-with-proxy.html

If you are specifying your organisation's servers correctly, and are still having these issues, then there is likely a firewall exception / SSL cert configuration issue that needs to be resolved, and is not a conda issue per se, but a networking problem

回答2:

You might want to try copying these files from Anaconda3/Library/bin to Anaconda3/DLLs :

libcrypto-1_1-x64.dll

libssl-1_1-x64.dll

回答3:

run these commands one by one....

$ export {http,https,ftp}_proxy="http://proxy-server:port"<br>
$ unset {http,https,ftp}_proxy

$ export {HTTP,HTTPS,FTP}_PROXY="http://proxy-server:port<br>
$ unset {HTTP,HTTPS,FTP}_PROXY<br>
$ source ~/.bashrc
