创建Vue项目vue-cli · Failed to download repo vuejs-templates/webpack: connect ETIMEDOUT

用vue-cli创建项目时显示超时，原因可能是github.com访问不了，用ping命令试一下，显示请求超时

点击查看github.com域名解析之后的ip地址https://github.com.ipaddress.com/，https://fastly.net.ipaddress.com/github.global.ssl.fastly.net

github.global.ssl.fastly.net

根据当前解析的ip地址修改本地的hosts文件，路径为C:\Windows\System32\drivers\etc\hosts，使用管理员身份打开，在后面累加刚才查看的ip地址

140.82.112.3   github.com
199.232.69.194   github.global.ssl.fastly.net

修改完之后的hosts文件为

# 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
