第一次用mac從我的github上導下項目，結果在修改之後想push上去的時候突然出現問題了，這部電腦之前是其他人用的，那個xxx就是他的賬號，出現該問題後，針對問題，一下子就百度出了一些解決方法，但是一一試過之後還是沒辦法解決，問題如下：
yidont:VtBanner mac_xihao$ git push origin master
remote: Permission to voctex/VtBanner.git denied to xxx.
fatal: unable to access 'https://github.com/voctex/VtBanner.git/': The requested URL returned error: 403我把我試過的一些方法都記錄一下：
1、清除ssh_key
打開終端，輸入
cd ~/.ssh然後就進入.ssh目錄了，輸入
ls查看目錄下文件
yidont:.ssh mac_xihao$ ls
config id_rsa id_rsa.pub known_hosts其中id_rsa是你的私鑰，而帶後綴pub的id_rsa.pub文件是你的公鑰，其中公鑰是要給服務器那邊配置的。
可以輸入open 用文件夾打開
yidont:.ssh mac_xihao$ open .我是直接把該目錄下的文件都刪了，然後重新生成公鑰和密鑰。
yidont:.ssh mac_xihao$ ssh-keygen -t rsa -C "[email protected]"(這裏建議輸入你的郵箱地址)
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/yidont/.ssh/id_rsa):
(這裏要你輸入存放的目錄，好像回車是默認，我沒試過回車)
/Users/yidont/.ssh/id_rsa
Enter passphrase (empty for no passphrase): (輸入ssh密碼)
Enter same passphrase again: （確認密碼）
Your identification has been saved in /Users/yidont/.ssh/id_rsa.
Your public key has been saved in /Users/yidont/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:1gepuxDHwJRnFbKvc0Zq/NGrFGE9kEXS06jxatPPrSQ voctex@163.com
The key's randomart image is:
+---[RSA 2048]----+
| ....=*oo |
| o. ooo=+ . |
| oo. =+o. |
| o =.o.. |
| . S =o. |
| = =++. |
| . B.=.Eo.. |
| o B . +o .|
| . o.. .. |
+----[SHA256]-----+
yidont:.ssh mac_xihao$ ls
id_rsa known_hosts id_rsa.pub 然後把pub文件裏面的值配置到你的github裏面的ssh_key
2、將git默認的遠程倉庫改爲你自己的那個，並且改掉host
yidont:.ssh mac_xihao$ git remote -v
origin https://git.oschina.net/xxx/YidontUtils.git (fetch)
origin https://git.oschina.net/xxx/YidontUtils.git (push)
yidont:.ssh mac_xihao$ git remote set-url origin https://github.com/voctex/VtBanner.git
yidont:.ssh mac_xihao$ git remote -v
origin https://github.com/voctex/VtBanner.git (fetch)
origin https://github.com/voctex/VtBanner.git (push)
yidont:.ssh mac_xihao$ git remote set-url origin git@github.com:voctex/VtBanner.git
yidont:.ssh mac_xihao$ git remote -v
origin git@github.com:voctex/VtBanner.git (fetch)
origin git@github.com:voctex/VtBanner.git (push)3、添加密鑰到sshAgent代理中
yidont:.ssh mac_xihao$ eval "$(ssh-agent -s)"
Agent pid 2172
yidont:.ssh mac_xihao$ ssh-add id_rsa
Enter passphrase for id_rsa: （輸入ssh密碼）
Identity added: id_rsa (id_rsa)
（測試連接到github網站）
yidont:.ssh mac_xihao$ ssh -T git@github.com
Hi voctex! You've successfully authenticated, but GitHub does not provide shell access.以上幾個方法都試過，都不能夠幫我解決問題，直到發現了這篇文章才解決了我的問題，

按照文章裏面說的，我在Android studio裏面的Terminal裏面進行操作，然後順利push了
yidont:VtBanner mac_xihao$ git remote -v
origin https://github.com/voctex/VtBanner.git (fetch)
origin https://github.com/voctex/VtBanner.git (push)
yidont:VtBanner mac_xihao$ git remote rm origin
yidont:VtBanner mac_xihao$ git remote add origin git@github.com:voctex/VtBanner.git
yidont:VtBanner mac_xihao$ git remote -v
origin git@github.com:voctex/VtBanner.git (fetch)
origin git@github.com:voctex/VtBanner.git (push)參考博客如下：
