Git新手常见问题总结

一. Please tell me who you are

1. 问题描述：初次使用git时，会遇到这样的提示

Please tell me who you are.
Run
  git config --global user.email "[email protected]"
  git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.

2. 解决：参考提示，在命令行运行如下命令，Tell git who you are

git config --global user.email  "[email protected]"
git config --global user.name "Your Name"

二. fatal: remote origin already exists.

1.问题描述：重复git remote add origin 同一个远程仓库时，会出现这个错误，可以理解为重复对origin进行绑定出错

2. 解决：

git remote rm origin 

三. 使用https://github.com/../..域名提交项目，会要求提交用户名和密码，用户名即github账号，密码即github的密码

四. Please make sure you have the correct access rights

1.问题描述：初次提交项目到远程仓库，会出现错误如下，原因是没有在远程配置本地密钥

Warning: Permanently added 'github.com,192.30.255.113' (RSA) to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights

2.解决：

1. 使用 ssh-keygen -t rsa -C "[email protected]"生成密钥
2. 在~/.ssh 目录下,有id_rsa，id_rsa.pub两个文件，把id_ras.pub的内容添加到github.com的账号下。
