在公司网络执行pod install时报错，网上查了各种关于443错误的解决方法，都没有解决我遇到的这个443问题，

fatal: unable to access 'https://github.com/facebook/ios-snapshot-test-case.git/': LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443

解决方案：
env命令设置GIT_SSL_NO_VERIFY环境变量为”ture”，并同时调用正常的git clone命令 或者 pod install命令

env GIT_SSL_NO_VERIFY=true pod install

成功解决我的443问题。
