1.通过ipaddress.com查询github.com域名对应的IP

将对应的IP地址添加到H将对应的IP地址添加到Host 文件中

2. 添加上面的内容后可能还会有部分资源倒不开

打开浏览器的调试窗口（F12）选择网络（Network）选中报错资源链接查看资源链接的域名eg: avatars0.githubusercontent.com 通过上面的地址查询IP 添加到Host文件中 逐一添加后显示正常

如下是我配置完的Host文件

# Copyright (c) 1993-2009 Microsoft Corp.
#
# 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

# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1                 localhost
