当输入git命令github项目时报错：
⇒ git clone git@github.com:/TX-Class.git Cloning into 'TX-Class'... Warning: Permanently added the RSA host key for IP address '13.250.177.223' to the list of known hosts. git@github.com: Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
错误①：
Warning: Permanently added the RSA host key for IP address '13.250.177.223' to the list of known hosts.
此错误参考：《git提交警告Warning: Permanently added the RSA host key for IP address '13.250.177.223' to the list of》
hosts文件的位置：
1、Mac：/etc/hosts
vim /etc/hosts
添加一行：13.250.177.223 github.com
但是修改完文件输入：：wq!时报错
Can't open file for writing
解决参考：《linux操作提示：“Can't open file for writing”或“operation not permitted”的解决办法》
修改文件命令时，应该用sudo
sudo vim /etc/hosts
再修改成功！！
错误②
fatal: Could not read from remote repository.
参考文章：《GIT 出现fatal: Could not read from remote repository.解决》
输入命令：
ssh-keygen -t rsa -C xxx@xxx.com xxx@xxx.com # 为你的github账号
一直按回车，什么都不输入。

再输入：
cd ~/.ssh
ls
# 如果有下面几个文件就成功了
id_rsa id_rsa.pub known_hosts
接下来打开github官网：选择设置
添加新的SSH key
复制新的key内容，输入：
pbcopy < ~/.ssh/id_rsa.pub
复制完粘贴到下面如图里
新的keys
最后就可以下载github中的SSH链接的项目了：
