一般輸入以下命令便可部署

git init
heroku git:remote -a 你的應用名稱
git add .
git commit -am "init"
git push heroku master

這個過程出錯，一般是報以下兩個錯誤

1.fatal: unable to access 'https://git.heroku.com/myforums123.git/': error setting certificate verify locations:
  CAfile: D:/Git/mingw64/ssl/certs/ca-bundle.crt

  CApath: none

2.Permission denied (publickey).

fatal: Could not read from remote repository.

解決方案:

步驟1.終端輸入ssh-keygen,檢視是否如下圖所示，

若顯示ssh-keygen不是內部或外部命令，則自行配製環境變數，確保輸入ssh-keygen如上圖所示

步驟2.滿足步驟1條件後，進入C:\User\.ssh (或者你直接在C盤 搜尋.ssh檔案)檢視該檔案下是否有以.pub為字尾的檔案

此時有兩種情況，

第一種就是你有這些檔案說明你有公鑰，需要將公鑰上傳到Heroku

第二種就是你沒有這些檔案，你需要新增一個公鑰

第三種就是刪除並新增heroku作為遠端引用

檢視現有的金鑰的方法是:

heroku keys
 

清除現有的金鑰的方法是:

heroku keys:clear

@第一種情況的解決方案

你需要把你的公鑰上傳到Heroku，進入

heroku keys:add ~/.ssh/id_rsa.pub (如果你已經進入.ssh目錄就不需要寫‘/.ssh’)

然後執行

git push heroku master

(不行的話使用

heroku keys:clear

 清除現有的金鑰，使用第二種情況的解決方案

）

@第二種情況的解決方案

使用以下命令新增一個公鑰

heroku keys:add

確保SSH檢查正確目錄中的金鑰，執行以下操作:

ssh -vT [email protected]

其中將顯示以下行:

OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007

debug1: Trying private key: /c/Wrong/Directory/.ssh/id_dsa
debug1: No more authentication methods to try.
 

再次執行

git push heroku master

命令應該能正確部署

@第三種情況解決方案:

1.先檢查heroku

git remote -v

如果heroku存在，將其刪除

git remote rm heroku

git remote add heroku [email protected]:project.git

再次執行下面的命令應該可以成功

git push heroku master
