ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy
configuration settings.

3.解决方案：

1.逐个输入以下命令，看是否在服务器上设置了代理

echo $http_proxy
echo $https_proxy 

unset http_proxy
unset https_proxy

cat ~/.condarc

我这边输入前4个没反应，输入最后一个命令后显示出此前设置了代理

2.执行下面的命令，删除代理

 conda config --remove-key proxy_servers

3.删除后再执行cat ~/.condarc命令，发现代理已被关闭

4.然后再正常执行创建conda环境的命令即可成功创建conda环境

 

5.执行conda activate envname命令激活conda环境 

ok，可以快乐编程了~~~
