Windows 下 git clone无法解析域名

遇到这种情况，应该在Windows全盘搜索 hosts 文件，该文件为Windows系统盘下某个名为/etc文件夹下，注意是Windows系统盘，并不是Git软件安装位置下的/etc文件夹。
找到该文件后，一般是不允许你做修改（系统盘文件夹做了权限设置），但是可以先把hosts文件拷贝到桌面打开做如下修改后再拷贝至原路径下。

# 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
# IP地址 域名，如下形式即可
192.168.1.1 gitlab.com

修改后可以在 cmd 窗口敲入如下命令进行测试，看看是否添加成功
即“ping 域名”

ping gitlab.com

出现正常连接结果则修改完成。
