本地建立git后，代码提交到版本库后。准备上传到github。
建立路径：

Birdy-2:learnGit birdy$ git remote add origin http://github.com/timothydsp/learnGit.git
Birdy-2:learnGit birdy$ git push -u origin master
fatal: unable to access 'http://github.com/timothydsp/learnGit.git/': Recv failure: Connection reset by peer

这里开始报错，不能连接
然后我尝试看链接地址有没有问题：

Birdy-2:learnGit birdy$ git remote add origin http://github.com/timothydsp/learnGit.git
fatal: remote origin already exists.

发现没有问题，尝试连接github：

Birdy-2:learnGit birdy$ ssh -T git@github.com
Hi timothysdp! You've successfully authenticated, but GitHub does not provide shell access.

能成功连接，再查看本地公钥是否存在：

Birdy-2:learnGit birdy$ cd ~/.ssh
Birdy-2:.ssh birdy$ ls
id_rsa        id_rsa.pub    known_hosts

检查线上公钥是否一样：

Birdy-2:learnGit birdy$ pbcopy <~/.ssh/id_rsa.pub

也应该没有问题吧？？？？？
到这里：

Birdy-2:learnGit birdy$ ssh -T git@github.com
Hi timothysdp! You've successfully authenticated, but GitHub does not provide shell access.

这样一圈下来为什么不能push，不能pull？

这里线上一能看到我的项目。

求各位前辈教教我，哪里出了错？

有大哥提到更换成HTTPS；或者ssh

Birdy-2:learnGit birdy$ git remote add origin https://github.com/timothysdp/learnGit.git
fatal: remote origin already exists.
Birdy-2:learnGit birdy$ git remote add origin git@github.com:timothysdp/learnGit.git
fatal: remote origin already exists.
Birdy-2:learnGit birdy$ git push -u origin master
fatal: unable to access 'http://github.com/timothydsp/learnGit.git/': Recv failure: Connection reset by peer

貌似还是不行~~
