解決辦法：
打開路徑C:\Windows\System32\drivers\etc下的hosts文件辆它，在文件末尾添加：
# GitHub Start
192.30.253.112 github.com
192.30.253.119 gist.github.com
151.101.184.133 assets-cdn.github.com
151.101.184.133 raw.githubusercontent.com
151.101.184.133 gist.githubusercontent.com
151.101.184.133 cloud.githubusercontent.com
151.101.184.133 camo.githubusercontent.com
151.101.184.133 avatars0.githubusercontent.com

# GitHub End
然后保存
如果在保存時出現(xiàn)禁止訪問嘴办，權(quán)限不夠冤议，需要在右鍵單擊hosts文件找到屬性-安全-編輯，添加用戶
然后在保存即可。
