git命令，拉个github的库还这么费劲，各种443失败

git clone :
error: RPC failed; curl 56 OpenSSL SSL_read: Connection was reset, errno 10054

git config http.sslVerify "false"

git clone :
Failed to connect to github.com port 443: Timed out

git config --unset http.proxy

git add ：
warning: LF will be replaced by CRLF in demo/demo.py.
The file will have its original line endings in your working directory

git config core.autocrlf true
