在克隆代码是出现访问不到github的情况

比如：

git clone https://github.com/WongKinYiu/PyTorch_YOLOv4.git

Cloning into ‘PyTorch_YOLOv4’…

fatal: unable to access ‘https://github.com/WongKinYiu/PyTorch_YOLOv4.git/’: Could not resolve host: github.com

打开终端，输入：

ping github.com

PING github.com (13.229.188.59) 56(84) bytes of data.

64 bytes from ec2-13-229-188-59.ap-southeast-1.compute.amazonaws.com (13.229.188.59): icmp_seq=2 ttl=44 time=278 ms

64 bytes from ec2-13-229-188-59.ap-southeast-1.compute.amazonaws.com (13.229.188.59): icmp_seq=3 ttl=44 time=279 ms

64 bytes from ec2-13-229-188-59.ap-southeast-1.compute.amazonaws.com (13.229.188.59): icmp_seq=4 ttl=44 time=284 ms

括号中的地址13.229.188.59就是github.com的实际地址.

将地址设置到配置文件：

sudo gedit /etc/hosts

原本的内容：

127.0.0.1	localhost127.0.1.1	ubun# The following lines are desirable for IPv6 capable hosts::1     ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters

将13.229.188.59 github.com写到里面：

127.0.0.1	localhost127.0.1.1	ubun13.229.188.59	github.com# The following lines are desirable for IPv6 capable hosts::1     ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters

再次使用git clone

git clone https://github.com/WongKinYiu/PyTorch_YOLOv4.git

Cloning into ‘PyTorch_YOLOv4’…
