Could not read from remote repository.

今天换新电脑，忘了配置git环境，就去gitserver上代替码。然后一直报错，后来就又一次配置了git环境。步骤例如以下

damingwuage:Desktop damingwuage$ ssh-keygen -t rsa -C "1011076472@qq.com"

Generating public/private rsa key pair.

Enter file in which to save the key (/Users/damingwuage/.ssh/id_rsa): (/Users/damingwuage/.ssh/id_rsa            

Enter passphrase (empty for no passphrase): 

Enter same passphrase again: 

Passphrases do not match.  Try again.

Enter passphrase (empty for no passphrase): 

Enter same passphrase again: 

open (/Users/damingwuage/.ssh/id_rsa failed: No such file or directory.

Saving the key failed: (/Users/damingwuage/.ssh/id_rsa.

damingwuage:Desktop damingwuage$ ssh-keygen -t rsa -C "1011076472@qq.com"

Generating public/private rsa key pair.

Enter file in which to save the key (/Users/damingwuage/.ssh/id_rsa): /Users/damingwuage/.ssh/id_rsa

/Users/damingwuage/.ssh/id_rsa already exists.

Overwrite (y/n)? y

Enter passphrase (empty for no passphrase): 

Enter same passphrase again: 

Your identification has been saved in /Users/damingwuage/.ssh/id_rsa.

Your public key has been saved in /Users/damingwuage/.ssh/id_rsa.pub.

The key fingerprint is:

ed:fc:a4:9d:28:8a:e3:65:43:a4:45:2e:95:39:a9:17 1011076472@qq.com

The key's randomart image is:

+--[ RSA 2048]----+

|      o+         |

|     +E          |

|    ..+o         |

|    .=.  .       |

|     .   o       |

|   .o... .o +    |

配置完毕后，

 将ssh key加入到GitHub中

用自己喜欢的文本编辑器打开id_rsa.pub文件，里面的信息即为SSH key，将这些信息拷贝到GitHub的Add SSH key页面就可以。
