【Mac + GitHub】之在另一台Mac电脑上下载GitHub的SSH链接报错

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。

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/[username]/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):

The key fingerprint is:
SHA256:HyXP86ndZiNVOchlHrHMriy5SoHredqReKwESZgtZx4 xxx@xxx.com
The key's randomart image is:

|   + E    . o =+o|
|    * o .  = o.+.|
|     + .S.. +  .o|

|       + *.o o+  |
|      o *.. o+ oo|

+----[SHA256]-----+

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：
