Could not generate ssh public key for heroku in Wi

问题:

While I am trying heroku login through cmd in my machine, it says

Could not find existing public key
Would you like to generate one? [YN]

After that when I press 'y' and enter it says

Generating new ssh public key
Could not generate key: "ssh-keygen" is not recognized as a internal or external command operable program or batch file

Please help me.

Heroku toolbelt includes git distribution which includes the required ssh-keygen.exe . I've just found it in C:\Program Files\git\bin . Locate your git folder and add it to your system path as described here: superuser.com/questions/284342/

I had the same problem and just solved it. I installed another CMD called Git Bash that you can download for free (http://git-scm.com/downloads) and then repeated the commands in that and it worked!

回答3:

For Win7 64-bit users, the file %HerokuPath%s\bin\ssh-keygen.bat looks like:

@SETLOCAL
@SET HOME=%USERPROFILE%
@"%HerokuPath%\..\Git\bin\ssh-keygen.exe" %*

But Heroku installs Git in Program Files (x86), so if you update the .bat file to:

@SETLOCAL
@SET HOME=%USERPROFILE%
@"C:\Program Files (x86)\Git\bin\ssh-keygen.exe" %*

Then you should be able to generate your ssh keys.

Windows 10-64bit

I had installed git, then heroku toolbelt (which I think reinstalled git)

I had C\Program Files (x86)\Heroku\bin in my Environmental variable (probably generated when I installed heroku toolbelt) and if I looked in that filepath I had an ssh-keygen.bat - so it seemed like I should be able to just run ssh-keygen -t rsa from the command line.

That would be too easy, instead I get:

C:\Program Files (x86)\Git\bin>ssh-keygen -t rsa -f id_rsa
'"C:\Program Files (x86)\Heroku\..\Git\bin\ssh-keygen.exe"' is not recognized as an internal or external command,
operable program or batch file.

Solution

type bash in command line to go into git bash mode then run ssh-keygen -t rsa

git bash:

mamwo@DESKTOP-9GVG6K8 MINGW32 /bin
$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/mamwo/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/mamwo/.ssh/id_rsa.
Your public key has been saved in /c/Users/mamwo/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:MMMYYYPPPUUUBBBLLIIICCKKEEEEYYYY mamwo@DESKTOP-9GVG6K8
The key's randomart image is:

Now when I look in C/User/mamwo/.ssh (the best way for me is through pycharms folder - windows sucks) I see my id_rsa and id_rsa.pub

But this 'cannot generate publickeys' issue all started for me because I had an 'I don't have public keys to add' issue when I cloned my repo (from github) to a new computer and found that I could push to github but not heroku.

Now that I have the keys - I have to add them

C:\Users\mamwo\Desktop\mv>git push heroku master
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

C:\Users\mamwo\Desktop\mv>heroku keys
You have no keys.

C:\Users\mamwo\Desktop\mv>heroku keys:add
Found an SSH public key at C:/Users/mamwo/.ssh/id_rsa.pub
Would you like to upload it to Heroku? [Yn]
