本地建立git後，程式碼提交到版本庫後。準備上傳到github。
建立路徑：

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

這裡開始報錯，不能連接
然後我嘗試看連結地址有沒有問題：

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

發現沒有問題，嘗試連接github：

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

能成功連接，再查看本地公鑰是否存在：

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

檢查線上公鑰是否一樣：

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

也應該沒問題吧？ ？ ？ ？ ？
到這裡：

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

這樣一圈下來為什麼不能push，不能pull？

這裡線上一能看到我的項目。

求各位前輩教教我，哪裡出了錯？

有大哥提到更換成HTTPS；或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

貌似還是不行~~
