1. 先ping通github.com(无法访问可能是访问的ip地址就不对)
1.1 先打开cmd窗口(win+R输入cmd后回车),看是否ping的通github.com
ping github.com
1.2 ping不通的解决
①如果ping不通,查看cmd上显示ping时访问的ip;
// 上面会有显示尝试ping到的ip(这个ip可能是错的)
②然后在这个网站上搜索github.com的正确ip地址(这个地址好像一直在变?所以不能直接cv网上教程里的ip),对比和cmd上的地址;
To:【My IP | IP Address Tools | IP Geolocation | Website Traffic Checker】
③若不同,则将查到的github.com的正确ip地址写进hosts文件最后一行。Reference:【一步步教你修改Windows本地hosts文件,轻松修改域名指向!_windows修改hosts-优快云博客】
// hosts文件本机路径:
C:\Windows\System32\drivers\etc\hosts
// hosts文件权限修改
右键hosts文件 > 属性 > 在/常规/中将"只读"取消掉
右键hosts文件 > 属性 > 在/安全/中编辑"权限"中的修改,勾选为允许
// 直接用记事本打开,修改为以下格式:
127.0.0.1 github.com
// 补充:如果hosts文件为空,直接cv下面文本到hosts文件即可(正常情况下,系统的hosts文件除了说明信息外,只包含“127.0.0.1localhost”这一段实际内容,大家都一样),再在后面修改github.com与ip的映射

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
2. 解决连接不上github或连接超时的问题:
2.1 取消 Git 的代理设置:
git config --global --unset http.proxy
git config --global --unset https.proxy
