【git基础-err】Permission denied (publickey). fatal: Could not read from remote repository.

problem

Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

分析

这种问题一般都是密钥设置不正确造成的，首先检查有没有在Git的网站上添加你本机的SSH key。
注意换了电脑是要重新添加的，每台都不一样。在用户主目录下，看看有没有.ssh目录，
如果有，再看看这个目录下有没有id_rsa和id_rsa.pub这两个文件，如果已经有了，可直接跳到下一步。
如果没有，打开Shell（Windows下打开Git Bash），创建SSH Key.

创建SSH Key:

Add SSH Public Key
    How to Generate an SSH Key
 
1. From the Terminal or Git Bash, run ssh-keygen
2. Confirm the default path .ssh/id_rsa
3. Enter a passphrase (recommended) or leave it blank.
Remember this passphrase, as you will need it to unlock the
key whenever you use it.
4. Open ~/.ssh/id_rsa.pub and copy & paste the contents into
the box below, then click on "Add".
Note that id_rsa.pub is your public key and can be shared,
while id_rsa is your private key and should be kept secret.

验证是否添加成功

$ ssh usrname@usremail
