git基础用法（三）----Permission denied(publickey)

    在某次的课程项目的开发中，想要从华为云的代码仓库上把某个分支的代码pull下来，但是碰到了一些问题，这些问题阻拦了我很久，我也收获了一些经验：

（1）could not read from remote repository

Devcloud: The project you were looking for could not be found.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

（2）Permission denied(publickey)

$ git pull origin master
\302\226git@codehub.devcloud.huaweicloud.com: Permission denied (publickey).
fatal: Could not read from remote repository.

    A "Permission denied" error means that the server rejected your connection. There could be several reasons why, and the most common examples are explained below.

    首先需要确定你是否生产了一个key:

eval $(ssh-agent -s)

    然后就是看你的密钥是否添加到了SSH中

$ ssh-add -l
The agent has no identities.

    这样就说明是错误的。

$ ssh-add /c/wamp/www/git秘钥/华为云课程
Identity added: /c/wamp/www/git秘钥/华为云课程 (/c/wamp/www/git秘钥/华为云课程)

    需要用到ssh-add命令来添加。

    之后就可以顺利的pull了。
