我已按照以下说明上传项目.

全球设置:

 Download and install Git
  git config --global user.name "Your Name"
  git config --global user.email tirenga@gmail.com
  Add your public key


Next steps:

  mkdir tirengarfio
  cd tirengarfio
  git init
  touch README
  git add README
  git commit -m 'first commit'
  git remote add origin git@github.com:tirenga/tirenga.git
  git push origin master

但我得到这个错误:

权限被拒绝(publickey).致命:远程端意外挂断

最近,我被添加为Github项目的成员/贡献者.我已经在本地机器上克隆了该项目.

我已经做了一些更改并在本地提交,现在尝试将更改推送到原始仓库但是当我尝试推送时,我得到一些权限错误？

C:\Users\MM\Documents\GitHub\software-licensing-php [master]> git push

# On branch master

nothing to commit, working directory clean

我是否缺乏推动变更的许可,所以我可以问项目的原作者？
