hi guys,

to get started with heroku, you need a public key. if you do not have one in the

c:\users\<yourusername>\.ssh folder, then you get this error

d:/program files (x86)/heroku/lib/heroku/auth.rb:195:in `read’: no such file or
directory – c:/users/romiko/.ssh/id_rsa.pub (errno::enoent)
        from d:/program files (x86)/heroku/lib/heroku/auth.rb:195:in `associate_key’

looking at the source code, line 195 is ssh key generation. so what we need to do is use a utility like gitbash to do this for us:

instructions

to get up and running with the heroku toolbelt on windows ensure you read:

http://devcenter.heroku.com/articles/quickstart

once you have read that and installed heroku toolbelt

http://assets.heroku.com/heroku-toolbelt/heroku-toolbelt.exe

then install git (or use the git bash if already installed)

http://msysgit.googlecode.com/files/git-1.7.8-preview20111206.exe

now, what you do is follow all the instructions here, you might as well ensure you have a github account, its nice to put your code in a repository if developing:

http://help.github.com/win-set-up-git/

you should then have these files (you might not have known hosts), if you did not connect into git

the heroku batch file will look for the id_rsa.pub file and use it to connect to the cloud servers.

once this is done, you can then go back to the heroku.cmd execution and login

d:\program files (x86)\heroku>heroku login
enter your heroku credentials.
email: romikov@gmail.com
password:
found existing public key: c:/users/romiko/.ssh/id_rsa.pub
uploading ssh public key c:/users/romiko/.ssh/id_rsa.pub

that is it, so hope this gets you started on heroku
