第一次用mac從我的github上導下專案，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

開啟終端，輸入

cd ~/.ssh

然後就進入.ssh目錄了，輸入

ls

檢視目錄下檔案

yidont:.ssh mac_xihao$ ls
config      id_rsa      id_rsa.pub  known_hosts

其中id_rsa是你的私鑰，而帶字尾pub的id_rsa.pub檔案是你的公鑰，其中公鑰是要給伺服器那邊配置的。

可以輸入open 用資料夾開啟

yidont:.ssh mac_xihao$ open .

我是直接把該目錄下的檔案都刪了，然後重新生成公鑰和金鑰。

yidont:.ssh mac_xihao$ ssh-keygen -t rsa -C "[email protected]"(這裡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):
(這裡要你輸入存放的目錄，好像回車是預設，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 [email protected]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檔案裡面的值配置到你的github裡面的ssh_key

2、將git預設的遠端倉庫改為你自己的那個，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 [email protected].com:voctex/VtBanner.git
yidont:.ssh mac_xihao$ git remote -v
origin  [email protected].com:voctex/VtBanner.git (fetch)
origin  [email protected].com:voctex/VtBanner.git (push)

3、新增金鑰到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)
（測試連線到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，

按照文章裡面說的，我在Android studio裡面的Terminal裡面進行操作，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 [email protected].com:voctex/VtBanner.git
yidont:VtBanner mac_xihao$ git remote -v
origin  [email protected].com:voctex/VtBanner.git (fetch)
origin  [email protected].com:voctex/VtBanner.git (push)
