错误1：git pull 出错 fatal: Could not read from remote repository.Please make sure you have the correct access rights.and the repository exists.

Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

出现这个问题是因为，没有在github账号添加SSH key

解决方法如下

在终端输入。

 ssh-keygen -t rsa -C "forwhat.cn"//注意。forwhat.cn为用户名

如果执行成功。返回

Generating public/private rsa key pair.
Enter file in which to save the key (/home/forwhat.cn/.ssh/id_rsa): 
在这里就是设置存储地址了.反正我是直接按的回车

然后还会返回

Enter passphrase (empty for no passphrase):

再次直接回车。
Enter same passphrase again:

再次回车。

Your identification has been saved in /home/forwhat.cn/.ssh/id_rsa.
Your public key has been saved in /home/forwhat.cn/.ssh/id_rsa.pub.
The key fingerprint is:
这里有一串数。我把他屏蔽了。
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
|                 |
|                 |
|    o            |
|   + .  S        |
|  . = .  o       |
|   o + +o.o      |
|E o . o.=+.      |
|.+   ==+ooo.     |
+-----------------+
这样SSH key就生成了。直接cat一下就好了。

000000:~/a$ cat /home/forwhat.cn/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQ(我屏蔽了)

把显示出来的直接添加到github账户设置里边的SSH keys
。add.

回来在git pull

就开始远程拷贝代码了

 错误2：Updates were rejected because the remote contains work that you do not have

git pull origin master
