vue init webpack-simple project 报错处理(connect ETIMEDOUT 192.30.253.112)

Failed to download repo vuejs-templates/webpack-simple: connect ETIMEDOUT 192.30.253.113:443

　　Failed to download repo vuejs-templates/webpack-simple: connect ETIMEDOUT 192.30.253.112:443，一直报这个错

解决步骤：

1.打开终端（cmd），输入命令：ping 192.30.253.112 发现连接超时；输入命令：ping github.com 显示超时。

2.打开 hosts文件，地址：C:\Windows\System32\drivers\etc  看是否是默认配置。默认配置如下：

# 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

　　如果不是，还原成默认配置。
